Chinook

Rotation at Blanche, AL and Little River, AL still looks impressive.

tornado-warned storm in the area of Gadsden has been impressive for several minutes. I am not sure if there has been any tornado.

I am seeing the velocities ramp up after Pachuta, Mississippi.

Possible tornado near Gorgas, AL (west of Birmingham) right now. This storm has tracked northeastward from Reform, AL area, with continuous tornado warnings.

by the way, the Hattiesburg area has had several tornadoes EF1-EF5 since 2000. Hattiesburg is in the middle of this image.

looks like 1-mile wide debris signature (Darbun, MS, west of Hattiesburg)

We must have had some interesting variation in snow rates. Loveland got 1" to 5.8" on CoCoRAHS. I had something like 1" -- some grass poking above the snow.

possible tornado at Oak Grove LA

These are the NAM-3km updraft helicity swaths out to 27 hours (03z Monday.) The NAM seems to like the idea of several storms in Arkansas, as opposed to MS/AL. I am not sure this is necessarily the most accurate depiction. Convection-allowing models are kind of all over the place with convection in MS. They seem to have a bit more agreement on several storms being MS/AL border near 00z, possibly extending the storms up towards Huntsville.

The hook echo was 2 miles from the radar. I have not heard any report of a tornado

Can I just complain for 4 seconds here? Why is it that the NAM, which is our best model for about 24-48 hrs for severe weather, can't forecast CAPE for crap?

Before we get to Sunday, the SPC's day-2 outlook has a 30% risk of hail in southern Texas, from the Rio Grande/ Eagle Pass area up to San Antonio vicinity. The outlook for wind is larger, but it's at 15%. 06z Sunday: dew points of 70F will be in the area of San Antonio with over 3000 J/kg of MUCAPE, with a most-unstable level above the surface. Even with the possibility of reduced shear due to elevated inflow, the 500mb winds will be around 65kt to 80kt, and there is turning of wind (SRH) between 1km and 3km. This is a very impressive CAPE for being 1:00AM-- many hours after sunset.

For our snowstorm, model QPF values are 0.4" to 0.8" for the plains, 1.0"-1.30" for mountains. I am pretty sure that winter storm warnings will be issued for areas of Wyoming, Nebraska, and the Colorado mountains above 9000ft. Northeast Colorado could get a winter weather advisory or possibly even a winter storm warning. Powering up this system, a shortwave trough in a strong northwesterly flow out of northern Canada. You could say that this is an arctic air mass in central Canada. Canada is usually some 25 degrees F warmer at this time of year.

Models are generally showing a deeper warm sector developing near a low pressure/warm front on Easter Sunday, 12z. I wouldn't be surprised to see some sort of outlook for central/east Texas on Saturday. As for Sunday, I would expect possibly an enhanced outlook for Louisiana, Mississippi, and Alabama.

4-panel radar with 70dBz hailstorm, 1.50" hail at Macomb reported

Possible tornado near Medina, OH

The ECMWF/GFS/Canadian are starting to agree on snow for Sunday and Monday, possible lows in the mid-20's Tuesday morning. It's unseasonable, but I guess there are no leaves on the trees just yet.

I believe we should start a new general severe weather thread, since it's a new decade.

I think I got 1.0" to 1.5".

Will storm chasers even be able to stay in hotels? I guess campgrounds could be open.

There have been 24-hr temperature change values of -41 to -51 degrees F between Denver, western Nebraska, and Cheyenne.

I think my place got 1.63" of precipitation in March, and 5.3" of snow. This is a slightly above average value of precipitation, even though Fort Collins-CSU got a little below average. Temperatures were just a bit above normal. This time of year generally the day of the maximum snowpack depth in Colorado, so I thought I might post some maps.

The GFS and the UKMET are still holding on to the forecast of several inches of snow at Larimer/Boulder Counties. The NWS expects > 3" above ~8000ft in Larimer County and areas closer to Casper, WY. It'll be a shocker, for sure. At my area, we had 70 degrees today.

Lenticular cloud. I have not gotten a picture of a lenticular cloud in the evening for a long time

A confirmed tornado was at Troy Alabama earlier, at 15:36z (Troy Airport)
