Chinook

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.

SPC's web page is breaking all over the place.

Radar base velocity shows up to 75 knots aloft heading for Nashville

There have been about 9 recent severe wind reports with this line of storms, nearing the Mississippi River.

Severe cell in SE Illinois near Shelbyville - radar data showed that 60dBz went up to 30,000 ft. Hail was estimated to be 3", but no hail of that size was reported.

We have had a couple of sub-severe storms out east of me today. The last 12 days have been above 60 here, with a high of 78, yesterday, a high of 81 on 4/27 and roughly 80 degrees today. Edit: the cold front has come in. In combination with some rain showers, the cold front has increased the dew point to 48 degrees. Summertime! Edit: my place has had some rain showers and distant thunder today.

I downloaded Nexrad level-2 data to make this 3-d image of the Moore tornado, 5/20/2013

I am pleased to announce that we will have a new thread for the summer. Today, it was 80 degrees here. The snow from several days ago is long gone. We probably will have above normal temperatures for several days. I hope we will have a summer with normal to above-normal rainfall.

Eastern Iowa could get several severe storms, with a chance for tornadoes. The SBCAPE may only reach 1000-1800 J/kg, which is generally kind of low, considering the SHARPpy-based soundings seem to have high CAPE numbers a lot of times.

I guess this is the TDS for the confirmed tornado near Rome, TN. it's possible the tornado went over I-40

Yesterday was the 9-year anniversary of some terrible tornadoes in NC, including this one that went through the city of Raleigh. I downloaded some data from NOAA to make this map. I hope this never happens again. The year of 2011 just had a way of making tornadoes go through cities.

Not sure if anybody replied Here's what I use

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.

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

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