Chinook

There's a new tornado warning east of Burkburnett. The original supercell regenerated the circulation.

I think this could be a large rain-wrapped tornado now, based on radar

a storm near Columbia SC may have 2" - 3" hail in it.

I guess this is the rotational signature west of Belmont, NC

14 tornado reports yesterday was the highest daily total since 4/23.

By the way, you and I got pictures of the same storm from a different perspective last night. (See Mountain West discussion)

Confirmed tornado outside of Garden City, KS with much more of a mesocyclone (within a blob of storms) compared to landspouts with a few storms before.

Holly, CO is under a tornado warning. There was one confirmed tornado southwest of the town. Holly had a direct tornado hit in 2007, so I hope nothing happens.

There was a bow echo that tracked northward to the Canadian border. At one point, there was an embedded circulation in the middle that had a tornado warning. It's pretty weird to see a bow echo not tracking eastward or southeastward.

I drove down the road to get a clear shot of this storm east of Fort Collins.

Yesterday, we had wind gusts of 30mph , up to 50mph at Denver, from the southeast. Today, Fort Collins has a dew point of 54, and SPC mesoanalysis shows 2000 J/kg of CAPE, although probably no rain will happen. The CAPE should shift up to Wyoming for the severe weather risk later. Edit: We've been drylined. The moisture is shifting to Wyoming.

We've had a couple of tornado warnings east of Pueblo CO that have been for confirmed tornadoes tonight.

Aside from the weird 500mb pattern, we could have some potential for supercells in SW Kansas and the Oklahoma panhandle on Day-3, and near the Red River on Day-4. The SPC has put eastern Wyoming in an enhanced risk for tomorrow. The NAM and Euro have convection at the same place in SW Kansas on Day-3, possibly a squall line.

We will have a narrow area of 80-95 degrees on the high plains on Tuesday, while the Mississippi Valley is cool.

There are 4 tornado warnings right now in the same area. In the past 3 days, there have been 3 tornado reports on the SPC storm reports.

This severe-warned storm is just about to go over I-25. My place just got rain for 10 minutes.

A tornado watch has been issued for parts of New York state.

A storm is getting going near Parker / C470 area. Maybe Mayjawintastawm can see that.

My area had a high of 61 and a low of 39 on Sunday. Yesterday, we had morning rain and evening rain. We had a high of 46 and a low of 35, which was quite below normal for this time of year. Today, it feels so much warmer, because it is partly sunny. We have a light wind but yet only 57 degrees, with a low of 39 this morning. Going back and looking at the MesoWest web site, my immediate area had a low of 37 on 5/8, a low of 37 on 5/6, and low of 35 on 5/5. Fort Collins temperature is at about average for the month. Models and forecasts generally show some showers and thunderstorms for our area on Thursday and Friday. Seasonal snowfall maps for Midwest/West. The Ohio Valley averaged 50% of average snow. Southern Colorado has now been put in to areas of D2-D3 drought, but no drought for northern Colorado, except an area of D0-D1 drought closer to Goodland, Kansas.

60 mph wind gust at Lima, OH (airport)

This is the 2nd snowstorm in the US, in 2 days

This isn't really Mountain West weather, but this is my first side-by-side comparison of Radarscope vs. GRLevel3. I decided to buy Radarscope. It has several nice features. There are definitely a few things that are different, but Radarscope has the super-resolution (Level-2) reflectivity. It has super-resolution (Level-2) base velocity, but I don't see storm relative velocity. So I guess I will still have to use GRLevel3's storm-relative velocity for some purposes, which is nearly at super-resolution. They have the same features for composite reflectivity. They have pretty similar features on the dual-polarization fields. GRLevel3 has better resolution on 1-hour rainfall and VIL. Radarscope has a distance measurement feature that makes a circle, showing miles. GRLevel3 has markers for measurement, and you get nautical miles. It's kind of funny that sometimes the maps show different small towns, but that's just the difference in the built-in maps from some national database. Storm tracks are a little different for some reason. Generally, I don't like the storm tracks, so I turn those off when I use GRLevel3. I pretty much just use hail icons in GRLevel3. Nice green hail icons make you think that every storm is throwing out 1"-2" hailstones 100% of the time. That's fun! GRLevel3 is more customizeable in terms of which types of warnings to show, which types of storm information to show (hail, meso, TVS), storm reports, and ability to load specialized color schemes. Radarscope has built-in support for MPING (cell-phone app where observers report any precipitation type, or possibly severe weather). I haven't found any severe storm report button (NWS).

We've had a max wind gust to 47mph here at Fort Collins- Loveland. We seem to be in a cool, dry, and sunny air mass, with low temperatures that could get down to 33 here.

The SPC has put out a day-3 slight risk for the Red River area. The forecast soundings have around 75 kt of 0-6km shear, if any (high-based) storms develop there. The College of Dupage GEFS page shows higher supercell indices on Wednesday 5/13 and Thursday 5/14, as well as several days beyond that. I don't know how many people usually look at the GEFS for this, but it might be interesting.

Just a few minutes ago, I saw the first nearby lightning bolts I've seen all year, with low rumbles of thunder. Several severe storm warnings were issued for NE Colorado this evening. Edit: my place had another thunderstorm at 11:00PM (previous was at about 10:00PM) with light to moderate rain, better thunder, and at several distinctive lightning bolts!! My rain totals are 0.30" and 0.26" for the last 2 days.
