April 2011 general discussion/obs thread


Hoosier

Recommended Posts

We ended up getting about 2 inches of snow yesterday along with thunder. The snow was very intense during the the thunder and lightning. I thought I would wake up this morning and the snow would be all melted but the ground still is still covered but probably not for much longer. The temp finally moved up into the low 40s after staying in the mid 30s most of the night. We also had quite a bit of lightning overnight. It's 70F in the southern part of the state while it's 41F here. I wonder if the warm air will make it here briefly. Probably not.

My forecast was for temps to rise into the upper 50s by dawn, but attm we're at 41. Warm front has not been as progressive as forecasted I guess (typical of this time of year, especially when you're on the northern side of the colder lake waters). Winds have just shifted SE as of 11z so I'm guessing it's finally pulled through.

I had my first non-snow associated thunderstorm of the year overnight too.

Fail. Back to ENE flow and temps stationary.

med range pattern looking much better then the past month or so.

Hey Alek, good to see that. I have a question that perhaps you or any of the experts in here can answer. Was on accucrap and saw Andersons blog and the euro weekly depicts cold over us. Last week it showed us cold for this upcoming week and we know that is not happening. Is the weekly euro kinda poor as far as reliability? I know the euro model in winter is solid where as the gfs tends to grasp summer patterns a little better.

Finally what is environmental canada seeing?

Thanks.

I don't follow the Euro weeklies and really rarely look at the Euro period outside tracking winter storms, but a quick glance doesn't look cold and IMO the GFS has been performing well since the last upgrade. Anyways, the upcoming week doesn't look cold to me, especially the later half.

That said, given climo and recent history, i wouldn't be shocked to see some of the warm fronts struggle to get as far north as being modeled right now.

Thanks Alek, should be some awesome looking yards with the warmth and rain....greening up rapidly in the sw burbs, cornelian cherry dogwoods are in bloom in my yard, they always bloom about 7 days before the forcythias.

we're running a little dry but with the pattern about to switch more active after a really dry mid feb-late march period, we should move back into normal territory.

I posted this in the svr wx thread, but figured I share it over here, too.

A line of thunderstorms came through here at 330am only a couple hours after we had heavy snow. I only saved the three best strikes.

Nice job Mike. I like the juxtaposition of the TSRA and the snowcover.

Today was a dud pretty much like I expected.

Welp, I'll be vanishing for the summer in the next couple of days. As always, it was a pleasure talking winter weather with you guys.

This is probably a non-sequitur...but I hope the severe wx is plentiful this spring/summer, while keeping the death/destruction to a minimum. I'll pop in if anything remotely interesting happens where I live, but it's unlikely. :lol:

Had a few showers last evening that mixed with sleet and a few mangled snowflakes for a couple of minutes. Wild weather indeed.

yeah i almost forgot about that, sleet/rain came down real heavy for about a minute or two. Hopefully it was winter's last gasp.

this is what i like to see

I don't think I've seen SE Wisconsin in the precip bullseye yet this year; that's why it won't happen.:arrowhead:

It's early spring, so the models may very well be bullish on warmfront progression north but i still like the signals for it to be wavering around the region this weekend.

We could see highs near 80F in Chicago on Sunday...crazy. A lot will depend on exact warm fronal placement, and of course it's 5 days out...but Gil Sebenste at NIU was even hinting at the Sunday warmth in his discussion yesterday.

wish it was Sat, but i'll take it. LOT already going with 76 for my point.

:wub:

Thursday Night: Showers and thunderstorms likely. Cloudy, with a low around 43. Chance of precipitation is 70%.

Friday: A 30 percent chance of showers and thunderstorms before 1pm. Mostly cloudy, with a high near 50.

Friday Night: A slight chance of showers and thunderstorms. Mostly cloudy, with a low around 44.

Saturday: A chance of showers and thunderstorms. Partly sunny, with a high near 53.

Saturday Night: Showers and thunderstorms likely. Mostly cloudy, with a low around 49.

Sunday: Showers and thunderstorms likely. Cloudy, with a high near 76.

Sunday Night: Showers and thunderstorms likely. Cloudy, with a low around 55.

9.2" of snow fell at ORD 29 years ago today, which is the daily record. I went and looked at the obs for LAF for that event...just a dimly lit moon.

Seriously though, 5.3" measured here by one of the COOP's.

:thumbsup: I bet it was dark that night, too.

Hard to believe 9.2" fell on this date...and that it dropped to 7F at ORD two mornings later with a fresh snowcover.

Only made it to 27º at LAF on the 6th and 30º on the 7th (with a low of 8º on the 7th). Impressive for early April.

The April 3/4 event did bring several bouts of thunder, but the storm total was 0.23" of rain and a trace of sleet.

Now, on April 5th, we have blustery winds and snow flurries. Tigers Home Opener just 3 days away!

April 5/6th have had several notable snowstorms in Detroit:

April 5/6, 2009: 7.2"

April 5/6, 1982: 7.4"

April 6, 1886: 24.5"!

Wow that's remarkable considering your locale and time of year. Goes without saying anything is possible and records are meant to be broken.

I was looking through the threads over at Eastern and found this gem from Feb 2007. Back when cromartie/tropical loved winter. :lol: And yes "wx" was one of his usernames.

MKE is sitting at -15.0 for the month of February so far (Feb 1-14).

Average high is 15.1 and average low is 2.0. Normal high/low for today is 33/18. With temperatures not expected to go to average until at least next Tuesday, this could be a top 10 coldest month for MKE easily.

This map is also simply amazing... I have to say the last 30 days sure did make up for the crappy Dec 10 to Jan 15 period.

Yes, the latest models are showing 18C @ 850 mb late Saturday into Sunday with the warm sector surging north across the upper midwest. When we hit 80 a couple days ago the 850 temp was only 13C.
