May 2023 Observations and Discussion

Recommended Posts

Today has a chance to reach the 80 degree mark across much of the County with the exception of some of the higher ridges in western sections. Shower chances increase especially over southern chesco by tomorrow morning. Sun returns on Mother's Day and we should see dry and normal to below normal temps for most of next week with the exception of Tuesday which looks to be several degrees above normal.
Records for today: High 91 (1911) / Low 31 (1907) / Rain 1.38" (1974)

We have some chances at severe thunderstorms this evening with the SPC painting Sioux Falls under the 'slight' risk. 'Enhanced' risk is not too far away, covering Sioux City and surrounding areas. NWS FSD seems to be a little hesitant about it but I'm crossing my fingers it all works out.

Currently under mostly cloudy skies with some sprinkles. Temp at 61 after a low of only 60. Pretty humid out there too.

Looks like you're gutter or downspout is plugged. I had to clean a couple of ours lately.

Congrats on all of the rains! 

 It was raining so hard that it was just coming off of the overhang/roof on the porch that doesn't have a downspout.  Checked the downspouts last week on the roof and they are all clear.

This is freakin' pretty rad to see daily storm chances across the higher terrain starting this Mother's Day weekend and lasting all throughout next week!  You don't see this quite often...this is very intriguing to see this happen at the time of year when PHX only averages 0.12" of precip in the valley.

Good luck to eastern Nebraska today.  The rain woes continue in mby with only .40 inches for the week.  Severe drought has now found it's way into my area.

Fingers are crossed here as this might be our last decent rain chance for the next week or so. 

So far this week's "active pattern" has delivered 0.15" of rain for my backyard... that's just not going to cut it this time of year.

Hmm, an interesting looking "clipper system" will dive due South out of the NW Territories of Canada late next week and make it into the GL's by the weekend ushering a significant cool down.  This will lead into a NW flow aloft and likely drive CF's through the region with more precip chances.  Memorial Day weekend starting to show a cooler pattern for the MW/GL's and the C & S Plains region where it'll be wet wet wet...

PWATs must be quite high now as some tiny showers dropped a surprising 0.21" this morning. Nothing measurable fell last evening/overnight. This was perfect to soften the crust on the garden from the previous hard rain last weekend.

Ha. Looks like we posted at the same time. Glad you got that much! 

Was it actually a thunder shower? Don't recall seeing any lightning strikes on the map for there.

I actually  didnt hear lightning.  But was really intense rain for 5 min and  very  ominous  clouds.  I like  the word "thundershower" but i hear its not correct  meteorologically  speaking. Was common when I was young.

@gabel23 did you get lucky from that line?

Had 3 tornado warnings in my county but luckily no official tornado on the ground. As far as the rain goes ended up with a total of .30” for the week. Mondays forecast was looking like 1-3 was a good bet. Drought goes on….

Yeah I also heard it's not correct, but I like to use that terminology for smaller or weaker cells since they're basically a shower with a little lightning and thunder, and aren't much of a storm.

Ended up getting some pretty decent lightning and thunder along with about a half inch of rain out the storms last night and this morning. Not too shabby.

More storms on deck for today, especially this afternoon. Everything has really greened up around here (can't believe how fast my grass is growing!) and any additional rain we can get will really help in that department. Praying for more!

Happy Mother's Day to all of the mom's out there today!! Well not much rain across Northern Chester County yesterday and not that much more...up to 0.10" across southern sections. So we continue to be running over 4" of rain below normal so far here in 2023.
More dry weather for the work week with temps rising to above normal by Tuesday before falling below normal by Wednesday through Friday. Next rain chance looks to be on Friday.
Records for today: High 92 (1900) / Low 30 (1996) / Rain 1.06" (1978)

Happy Mother's Day to all the wonderful Mom's out there.  Hopefully mother nature is cooperating for your festivities today!

Out here in the Valley of the Sun, we will be doing just that...Baking in the Sun!  Heading up to 100F with full Sun this morning and sitting at balmy 78F at 7:11am...while we are enjoying the sun in the valley, it's a different scenario up in the mountains.  I was driving around the valley yesterday and looked north at the views towards the mountains and the clouds certainly looked like the Monsoon season is off to an early start with towering cumulonimbus clouds.  It doesn't typically begin till late June but maybe this year it's starting early?  Some mets aren't saying so but i believe it is natures way of saying "Yes"!  I'll try and capture some photos throughout the week as storm chances are on the rise by midweek.

This weekend has been a pretty big disappointment, rain-wise.  Since Thursday we've only received 0.21".  Today was looking like our big day, but instead the heavy rain ended up well to the north and east.  The upcoming week looks dry, so we will likely fall below average for the month.

Here's  my  precip numbers from 2023 so far.

Jan - 2.23

Feb - 3.07

Mar - 2.08

Apr - 2.46

May - .86 so far

Today I  planted 3 large trees.  Basically  18 inches down almost void of moisture.   The trend since 2012 looks to continue. Other than a handful  of very wet weeks and a wet day or two per month the growning season my area in general here has been dry dry dry! Some of our wettest periods since 2011 have been in sept or oct. But some winter months way way wetter than avg. Basically  it rains but rarely when we need it! I used to trust May for 4 inches or more but apparently  thats becoming  a thing of the past!  July  and Aug here have become shockingly dry, as well as some Septembers and June. Even Aprils have been so dry at times grass will barely  grow. Again all of this Im comparing to averages  for Ottumwa  Iowa I assume  over 60 years?  We started our business  here in 2008 and for the first 4 years lack of rain never entered  our minds!  I still cant believe  today that we were getting  mowers stuck back then in places  haven't  even barely  been wet for years now.  Most ponds  haven't  been full  for 18 months or longer now. About 3 yrs ago I saw a report on National Geographic  Channel  discussing Iowa flooding.  The report basically  said that growing  crops in Iowa is becoming  almost  impossible and insinuated that world food supplies  will be affected by all the flooding in constantly  in Iowa!  MUCH OF IOWA BEEN IN DROUGHT SINCE I SAW THAT!  In my area here  lack of july aug moisture  has reduced yields  somewhat.  But flooding? What is that? Map below is past 30 days rain.
