chescowxman Posted February 2 Report Share Posted February 2 Happy Groundhog Day to those that celebrate! No shadow this year so spring is around the corner....or maybe not! Some light rain overnight with County totals including East Nantmeal 0.13" / Atglen 0.11" / Chester Springs 0.14" / Glenmoore 0.14" / Devault 0.11" / West Chester 0.12" / London Grove 0.11" and Kennett Square 0.09", Looks like some great winter weather on tap for much of the upcoming week with sunny skies and seasonably chilly but not cold temps. A nice break after all the drearies!

MIKEKC Posted February 2 Report Share Posted February 2 Another rain storm is on its way for KS and MO. KC looks to see somewhere between .25 and 1 inch of rain which is a lot for early FEB. We are already way above average since DEC. 1st. We have received 8-13 inches of snow across the city so far. For now, its Spring! Very warm, temps in the 60's this week...Hoping that turns around here towards the middle and end of the month with some cold and snow. I'm not worried about the storm systems as there have been plenty in this pattern and the Dec. 25th to Jan. 20th part of the pattern is ramping up again. Let's see how all this cycles back through. Let's finish strong winter! I'll take one more 3 week stretch like the January run any time. BTW, Lezak says our best shot at another run will be Feb. 18th through March 10th. 1 1 Quote Link to comment Share on other sites More sharing options...
Beltrami Island Posted February 2 Report Share Posted February 2 50 minutes ago, westMJim said: 1996: An Arctic outbreak that lasted from late January through early February produced nearly 400 hundred record lows, 15 all-time low readings, and over 50 new record lows. Four states recorded their all-time record low temperatures, including Tower, Minnesota, on this date with a reading of 60 degrees below zero, canceling Tower’s annual Icebox Days festival because it is too cold. Locations that reported their all-time record low or tied included: Cresco, IA: -36°, Osage, IA: -34°, Charles City, IA tied their record low with -32° and Lancaster, WI tied their all-time record low with -31°. International Falls, MN, and Glasgow, MT set records for February with -45° and -38°, respectively. The temperature at Embarrass, MN, plummeted to -53°. Rochester, MN, dipped to -34° for its coldest temperature in 45 years. A few random facts I've picked up about the about the Tower, MN -60 reading. The snow depth at the site was 44" meaning the reading was taken way lower than the standard 5 feet above the ground, biasing the reading low. The actual reading was -59.5, if normal rounding rules are applied a 5 should be rounded up the next largest integer, well for a -59.5 the next largest integer is -59 not -60. But -60 sounds better and was accepted. The thermometer at the typical cold spot in that area, Embarrass, broke during the night, it can be assumed based on past and subsequent readings then that Embarrass was probably colder. Also in only 6 days Tower warmed to +48f for a 108 degree swing in 6 days. The 44" snow depth is absolutely bonkers as well. Tower is far away from Lake Superior so it has no lake enhancement, it is also is relatively flat having no geographic orthographic lift to aid snowfall. The 44" snow depth is driven purely by synoptic scale weather. One more weird fact, I was a kid at the time and lived closer to the twin cities than northern Minnesota. But, my dad was on a snowmobile trip staying about 30-40 miles from Tower that weekend. There really wasn't much riding to be done, just getting the snowmobiles started was a task. Only carbureted sleds would even start, the first generation fuel injected snowmobiles of that time would not start at all. 3 Quote Link to comment Share on other sites More sharing options...
tStacsh Posted February 2 Report Share Posted February 2 59 minutes ago, Niko said: Big warm-up coming next week. My area could potentially hit 50F. Still some large snow piles around. Great thing is that sunshine will be returning by tomorrow (ahhhh, some Vitamin D). Temps remain AB until further notice. Now this is my kind of mid to late winter. It definitely can get cold and snowy in late February and early March, but by then it doesn't last long. I'm going to enjoy the sun this weekend. It's been almost 2 weeks. 1 Quote Link to comment Share on other sites More sharing options...
Tom Posted February 2 Author Report Share Posted February 2 Yesterday, it was the 3rd day in a row that PHX hit a high of 81F! It's not often you get temps to max out in the low 80's in the winter...is 81 the lucky number? Last night around 7pm the valley was blessed with quite the rainfall as my area yet again was the bullseye (1.30 of RN). The east valley got hit big time while PHX had about 0.53" of welcomed rain. What a turnaround after such a dry Autumn. The blocking and STJ really fired up around here and hopefully it can continue late into the Spring. 1 Quote Link to comment Share on other sites More sharing options...

Black Hole Posted February 2 Report Share Posted February 2 I'm exactly at 11" for the water year so far, which is just slightly above average.

The window has been pushed back a little, but I think Gary's timing that was mentioned above is about what I would say right now. Around the 18th or so and onwards we should at least see a return to colder weather and snow for some.

I was living in New Brighton at the time and had -34F on a wired thermometer. That's D**n cold for a relatively close suburb of the UHI of MSP. 1 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

I am skeptical of any measurement of -70 with a handheld thermometer but absolutely believe -70 or lower is possible. NE Minnesota extending up into Ontario has so many little pothole boxed canyon type backwater/swamps (if that makes sense) where under the right conditions cold air just continuously flows down too them like a river connecting a series of lakes, each one colder than the last.

Totally agree on those pot hole spots you mentioned. A relative new Coop site is Cotton,MN just N of Cloquet on 33. In a spruce swamp. I haven't checked this year because it's just hasn't been that cold and they many no longer be reporting, but a few years back they were significantly colder than classic spots. I believe -54 or something like that. Who knows what they wouldve been in 1996. Jan of 1994 is another one that gets overshadowed by Feb 1996. It was overall much colder. I believe Crookston had a avg temp of -6F for the entire month. Places in E ND were even colder. 1 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

Niko Posted February 2 Report Share Posted February 2 Pattern change coming for the 2nd part of February as it will turn much colder and snowier for some parts of the country. The EC stands a good chance as well. February tends to be their snowiest month of the winter season. Right now, March looks quite cold and potentially snowy, which could last through the end of the month, b4 winter says good bye. 2 1 Quote Snowfall for Winter 2023 -24 for Metro Detroit Area Oct 2023: 0.2" AN Nov 2023: 2.2" AN Dec 2023: 0.5" BN Insane!

westMJim Posted February 3 Report Share Posted February 3 Will have to see how the next 10 days play out but, but if the forecast is correct this could be the warmest start to any February since 1991. In 1991 after a below average day on the 1st there were 9 days in a row of above average temperatures. Highs reached the 50's on 3 days in a row. The official H/L yesterday at Grand Rapids was 37/27 that 27 was the coldest low since January 22nd and it was also the 1st time it has gotten below 31 in that same time. There was no rain/snow yesterday as it was the sunniest day in a long time with 45% of possible sunshine. For this winter season Grand Rapids is now at 34.5” of snowfall that is -17.7” on the season. For today the average H/L is 31/18 the record high of 54 was set in 1991 and the record low of -17 was set in 1996.

chescowxman Posted February 3 Report Share Posted February 3 Things have been slower on the work front so finally had a chance to download and consolidate all 23 available Chester County climate data sites (see below table for detail). All stations have been weighted equally for all years they were reporting data . I then compared the all average temperature by decade data to the NCEI NOAA Chester County PA average temperatures reported by decade. As expected the greatest downward post observation adjustments to the data were during the warmest raw data reported decades of the 1930's and 1940's with a gradual reduction in cooling that started in the 1950's finally resulting in what are now warming adjustments during the most recent 2 decades. 2 Quote All historical weather data analytics posted by me is specifically for the climate of Chester County PA.

jaster220 Posted February 3 Report Share Posted February 3 ++FROSTY overnight up here. Normally this will burn off shortly after 9 but after noon it was still going strong. The middle photo is Dead Stream Swamp on the west side of Houghton Lake. It's lower elevation and the fog was still noticable in that stretch. Otherwise wall-to-wall sunshine is finally visiting The Mitt!! 3 Quote Winter 2023-24 Snow Total = 53.1" (90% Normal Season) Largest Storm: 12" (1/12-13) Oct: 0.1 Nov: 2.9 Dec: 7.5 Jan: 31.7 Feb: 6.0 Mar: 4.3 Apr: 0.1 Avg = 59.2" (Harrison): 2023-24 = 53.1" Avg = 45.0" (KDTW): 2022-23 = 33.5" 2021-22 = 35.6" Avg = 49.7" (KRMY): 2020-21 = 36.2" 2019-20 = 48.0" 2018-19 = 56.1" 2017-18 = 68.3" 2016-17 = 52" 2015-16 = 57.4" 2014-15 = 55.3" 2013-14 = 100.6" (coldest & snowiest in the modern record!) 2012-13 = 47.2" 2011-12 = 43.7" Legit Blizzards (high winds and dbl digit snows): Feb 2011, Dec 2009, Jan 2005, Dec 2000, Jan 1999, Mar 1998, Nov 1989, Jan 1982, Jan 1978, Jan 1977, Apr 1975, Mar 1973, Jan 1967, Feb 1965, Jan 1918 Link to comment Share on other sites More sharing options...

All stations have been weighted equally for all years they were reporting data . I then compared the all average temperature by decade data to the NCEI NOAA Chester County PA average temperatures reported by decade. As expected the greatest downward post observation adjustments to the data were during the warmest raw data reported decades of the 1930's and 1940's with a gradual reduction in cooling that started in the 1950's finally resulting in what are now warming adjustments during the most recent 2 decades. Meaning what exactly? Someone smoothed the curve at the expense of actual reality?

Yes - NOAA made post observation adjustments to the raw data. I have discussed these adjustments for years but I am told they have their valid reasons for the adjustments but I have never been a big fan of this as if the data was deemed valid at submission why adjust years after the fact? 1 Quote All historical weather data analytics posted by me is specifically for the climate of Chester County PA. We continually analyze the actual raw non-adjusted NWS certified Coop observed climate data for Chester County. There have been no post observation adjustments to any of the detailed analytics.

Hawkeye Posted February 3 Report Share Posted February 3 We made it to 56º a couple days ago, but yesterday and today thick, low stratus killed our temp. We were stuck in the mid 30s yesterday and the temp has gone nowhere again today... both days well before the forecast. 1 Quote season snowfall: 34.8" '22-23: 30.2" '21-22: 27.1" '20-21: 52.5" '19-20: 36.2" '18-19: 50.2" '17-18: 39.5" Average snowfall: ~30" Link to comment Share on other sites More sharing options...
Minny_Weather Posted February 4 Report Share Posted February 4 Pretty sure by the start of next week we'll finally be back to seasonal temps here in MN. Not necessarily cold, but seasonal. The bulk of any precip we will receive in the next 10 days will be rain which is not a concern I should be having in February. 2 Quote Formerly *ahem*: LNK_Weather, TOL_Weather, FAR_Weather, MSP_Weather, IMoveALot_Weather.

The biggest snowfall of 10.0” fell in 1900 the most snow on the ground was 20” in 1959. Last year the H/L was 35/9 and there was 5” of snow on the ground. The overnight low here in MBY so far has been 22. And that is the current reading Quote Link to comment Share on other sites More sharing options...
Tom Posted February 4 Author Report Share Posted February 4 This is interesting...Final SSW event for the season??? Big reason that this Winter season is going to have some back loaded legs....I remember a warming event like this one in mid FEB that delivered the "Beast from the East." I'm wondering if this sets the stage for a "Marvelous March"...in terms of Big Snows....this has potential for some interesting Winter shenanigans. 3 Quote Link to comment Share on other sites More sharing options...
