Tom Posted April 25, 2018 Report Share Posted April 25, 2018 Who's ready to flip the calendar into May? After what has been truly a historic April in terms of snow & cold weather for much of the nation, I'm sure everyone on here has had enough of Ol' Man Winter. It's time we focus on gardening, outdoor activities, and last but not least.....shall I say...Severe Wx????. Is mother nature going to provide us with a phenomenal open to the month? Yes...a nice reprieve is on the horizon and this should kick start planting season across our ag belt. Let's discuss.... The Euro Weeklies have been quite dry in recent runs but is now trending towards a wetter pattern Week 2-3 which fits the LRC quite well. I wasn't really buying into the dry look it has been advertising of late. There should be several chances of severe weather mid and late month across our sub. As the long term long wave trough cycles through during the middle of the month, I'm expecting to see several frontal systems which will lead us into a increased likelihood of severe weather. Meantime, most models are advertising the 1st 80F day of the year for a lot of us in the Plains/MW region....this is going to feel fantastic. 3 Quote Link to comment Share on other sites More sharing options...

BrianJK Posted April 25, 2018 Report Share Posted April 25, 2018 After what has been basically a long dragged out non-existent winter around these parts (sans the one week in February), I’m ready for the sustained warmth. Chicago’s last subfreezing high was back on Feb 12th which is more than a month earlier than normal. Think it’s safe to say that will hold, as the extended looks to flip to a more spring/summer like pattern (finally). 2 Quote Link to comment Share on other sites More sharing options...

Minny_Weather Posted April 25, 2018 Report Share Posted April 25, 2018 Only severe weather day I can see is next Tuesday. Monday looks intriguing to our West but the capping is too much here. Tuesday has borderline CAPE and weak lower level shear but good upper level shear. I'm thinking it will be an isolated threat and the main issue will be large hail and straight line winds. Helicity looks just simply too low for an appreciable tornado threat. This is all per GFS. Quote Formerly *ahem*: LNK_Weather, TOL_Weather, FAR_Weather, MSP_Weather, IMoveALot_Weather.

CentralNebWeather Posted April 25, 2018 Report Share Posted April 25, 2018 My gauge had right at 1 inch yesterday. Some areas got much less than that so I feel blessed that we got that much. Beautiful today, and as I look out of my classroom window there are dandelions sprouting outside.

Tom Posted April 26, 2018 Author Report Share Posted April 26, 2018 An active pattern sets up mid/late next week as several waves of precip are being suggested across the ag belt. After a cold weekend, the much anticipated warm up Mon-Wed provides the fuel to fire up some storms as a typical Spring-like pattern sets up as a frontal boundary draped across the sub froum ushers in several chances of precip next week allowing for a good soaking.

Tom Posted April 26, 2018 Author Report Share Posted April 26, 2018 Big changes across North America being predicted per the CFSv2 for this month. Since the 16th of this month, the advertised ridge across Hudson Bay is being replaced steadily by a trough. Interestingly, temp trends are comparatively similar, although, I'd be weary about them to trend cooler if that vortex-like feature stays put. It would likely suggest plenty of frontal systems to rotate down into the U.S bringing bountiful precip chances and not the dry look. http://www.cpc.ncep.noaa.gov/products/people/mchen/CFSv2FCST/monthly/images/CFSv2.z700.20180416.201805.gif http://www.cpc.ncep.noaa.gov/products/people/mchen/CFSv2FCST/monthly/images/CFSv2.NaT2m.20180416.201805.gif recent run... http://www.cpc.ncep.noaa.gov/products/people/mchen/CFSv2FCST/monthly/images/CFSv2.z700.20180426.201805.gif http://www.cpc.ncep.noaa.gov/products/people/mchen/CFSv2FCST/monthly/images/CFSv2.NaT2m.20180426.201805.gif http://www.cpc.ncep.noaa.gov/products/people/mchen/CFSv2FCST/monthly/images/CFSv2.NaPrec.20180426.201805.gif Quote Link to comment Share on other sites More sharing options...
Tom Posted April 26, 2018 Author Report Share Posted April 26, 2018 JMA Weeklies agree with Week 2 cooling and suggesting a very transient weather pattern overall this month. Typical yo-yo temp pattern and a "step ladder" climb into Summer. Weeks 3-4 pretty normal overall and not showing any distinct signs of a torch or cold pattern locked in.

Around here, unless you know how to read a rotation radar, you have less than 1/4 mile visibility (if lucky enough to have daylight) and plenty of projectiles in the form of trees. Some folks here still don't know the difference between a watch and a warning. Once past Tulsa, our newscasters don't seem to care much.

Tom Posted April 30, 2018 Author Report Share Posted April 30, 2018 Some pretty big changes per the CFSv2 for the month of May. Blocking disappears and a huge ridge builds across the CONUS. I'm skeptical of the location of the ridge near the GL's/MW. The cycling pattern of the LRC suggests to me that those farther north and east in our sub forum will see many troughs swing through and plenty of chances of precip this month. I could see the heat really build across the central/southern Plains and into the MW right around Memorial Day and last through month's end setting up a hot start to summer down south. Should be an interesting mid/late month with an active period of severe weather May 7th thru Memorial Day weekend. We may conceivably see chances of storms every 2-3 days across the sub forum beginning Week 2 into the last week of the month. Some will get hits, some not, that's the way it goes. http://www.cpc.ncep.noaa.gov/products/people/mchen/CFSv2FCST/monthly/images/CFSv2.z700.20180429.201805.gif http://www.cpc.ncep.noaa.gov/products/people/mchen/CFSv2FCST/monthly/images/CFSv2.NaT2m.20180429.201805.gif Very wet across the central/southern Plains... http://www.cpc.ncep.noaa.gov/products/people/mchen/CFSv2FCST/monthly/images/CFSv2.NaPrec.20180429.201805.gif Quote Link to comment Share on other sites More sharing options...
Minny_Weather Posted April 30, 2018 Report Share Posted April 30, 2018 OAX coming out with the strong wording. With a triple point in the picture and a sudden spike in EHI values, wouldn't be surprised to see SPC give us a moderate risk either this afternoon or tomorrow. Focus shifts to the developing severe threat Tuesday afternoon andnight as the front moves to a position just north of I80 by earlyevening. Atmosphere may be largely capped until about 21z, withsignificant thunderstorm development likely along the I80corridor. Surface dewpoints could be in the lower 60s by then,with 0-6km bulk shear values increasing to around 50 knots.Surface-based CAPE of up to 2500 J/kg, combined with strongconvergence along the surface front should lead to supercells insoutheast NE, expanding in coverage through the evening. Surfacewinds will be slightly backed, enhancing helicity, with veeringwinds aloft, Soundings suggest critical angles of low level shearand storm relative winds will be nearly perpendicular, resultingin a high likelihood of tornadic supercells initially. GFS evenindicates there could be a magic triple point initiation perhapswest or southwest of Lincoln. Storms should expand in coveragenorthwest along the frontal boundary which becomes nearlystationary through the evening. SPC has maintained areasalong/south of Interstate 80 in an enhanced risk for severe stormsTuesday afternoon/evening, with a 10% probability of tornadoes,which could be significant (EFT or greater). Locally heavy rainwill be possible with storms Tuesday as well, with WPC continuingto highlight a slight risk of excessive rainfall. However, thearea also remains quite dry, ranging 2-3" below normal over theprevious 30 days, so the rain will also be beneficial and needed.The severe threat diminishes after midnight south of I80, withheavy rain the predominant threat by then.Even NAM is less of a fly in the ointment, even though 3km still has main development North of us. I think that's wrong considering where the triple point will be. Quote Formerly *ahem*: LNK_Weather, TOL_Weather, FAR_Weather, MSP_Weather, IMoveALot_Weather.

NEJeremy Posted April 30, 2018 Report Share Posted April 30, 2018 I'll be heading out tomorrow for a 2 day chase. Tomorrow I've been watching the intersection of the cool front and dry line and what looks like even a nice dry line bulge right south of that intersection. The models have pretty consistently showing that down in Kansas, but of late have been shifting this further northeast. My target tomorrow is somewhere south of York along the NE/KS border. If the 12Z NAM is right, a nice looking cell should track east along the border or into southern Nebraska and after 6p tornado potential really ramps up.The 12Z GFS is even further north and east into Nebraska to the west and southwest of Lincoln. I'm going to go just east of wherever that intersection of the dry line and cool front is.Further south along the dry line has potential, but I'm worried about a blue sky bust even though the parameters look nice. It would be sweet to have a lone supercell with no other storms for miles.For Wednesday, this was looking like the big day, but I'm not so certain anymore. The NAM models aren't really spitting out much, but the GFS is better now. Atmosphere is strongly unstable and uncapped over most of Oklahoma and Kansas, but it appears the main piece of energy might arrive too late. However, with that amount of instability and no cap, it won't take much to pop something. Wind profiles aren't overly good though until much later. The 12Z GFS does now show a shortwave moving into western OK and southern KS about 6p, so maybe that will be enough to save the day. Quote Link to comment Share on other sites More sharing options...
NEJeremy Posted April 30, 2018 Report Share Posted April 30, 2018 This is quickly turning into a possible tornado outbreak scenario for tomorrow. GFS soundings have PDS tornado wording. We'll get a moderate risk without question.I'd be careful with the PDS soundings. They seem to be pretty arbitrary on when they pop up in the soundings. I've seen them show up with very average parameters, but the LCL's are super low. I've seen sky high shear numbers, but no PDS sounding. Never seen the exact requirements for a PDS sounding to show up.That being said, the SPC mentioned a strong tornado possible. They kept the enhanced risk too with the latest update. I'm not sure the coverage of storms will be enough for a true outbreak. There doesn't look like there will be a lot of storms at least initially in the afternoon and early evening. There's not a lot of forcing tomorrow. SPC mentions neutral or even rising heights. Of course, individual storms are better for tornadoes than a mess of storms in a line, but the models seem relatively "dry" for tomorrow afternoon and evening. 1 Quote Link to comment Share on other sites More sharing options...

It's been sorta a policy of mine that I don't go out if there's a legit threat of severe weather over my place. Hope you get some good stuff Jeremy! I'd set up East of the triple point about 50 miles South of the cold front. 1 Quote Formerly *ahem*: LNK_Weather, TOL_Weather, FAR_Weather, MSP_Weather, IMoveALot_Weather.

Minny_Weather Posted April 30, 2018 Report Share Posted April 30, 2018 I'd be careful with the PDS soundings. They seem to be pretty arbitrary on when they pop up in the soundings. I've seen them show up with very average parameters, but the LCL's are super low. I've seen sky high shear numbers, but no PDS sounding. Never seen the exact requirements for a PDS sounding to show up.That being said, the SPC mentioned a strong tornado possible. They kept the enhanced risk too with the latest update. I'm not sure the coverage of storms will be enough for a true outbreak. There doesn't look like there will be a lot of storms at least initially in the afternoon and early evening. There's not a lot of forcing tomorrow. SPC mentions neutral or even rising heights. Of course, individual storms are better for tornadoes than a mess of storms in a line, but the models seem relatively "dry" for tomorrow afternoon and evening.Yeah I posted that without looking at simulated reflectivities. Granted, I'm never really trusting of what NAM says as it has the tendency to be wrong from what I've seen. I'll believe one particular thing when HRRR comes into range tomorrow.

Those are pretty neat to be able to see helicity tracks.Go under models, and then under convection allowing models. There's 3 other models, other than the 3km NAM and the HRRR.I use these a lot to try and see if there will be a lot of rotating storms. http://www.pivotalweather.com/model.php?m=hrwarw&p=uh25_max&rh=2018043012&fh=1&r=us_c&dpdt=http://www.pivotalweather.com/model.php?m=hrwnmmb&p=uh25_max&rh=2018043012&fh=1&r=us_c&dpdt=http://www.pivotalweather.com/model.php?m=hrwnssl&p=uh25_max&rh=2018043012&fh=1&r=us_c&dpdt= 2 Quote Link to comment Share on other sites More sharing options...
