-At least 10 tornadoes are reported in Oklahoma.
-SPC lists 37 tornado reports Monday. Many of those are likely duplicate reports of the same tornado.
-At least 5 people were killed in Oklahoma. There were dozens of injuries.
- We do not yet know what data VORTEX2 captured Monday, but it appears a tornado passed within .7 mile of the VORTEX2 headquarters in Norman. That tornado went on to cause fatalities. It will be interesting to see where the mobile units were deployed when the tornado was within sight of the VORTEX 2 headquarters.
Impressive tornado "couplet:"
Check out the image below which shows a clear tornado couplet on doppler velocity data scan.
NWS doppler radar image shows clear "tornado couplet" where red and green colors meet northwest of Seminole, Oklahoma.
The NWS office in Tulsa, Oklahoma has a nice summary of the days events.
NWS survey teams are in the field today to assess the number, paths and EF Scale intensity of the various tornadoes in Kansas and Oklahoma. Stay tuned for more results as the data pours in.
Now that's what we call a long slow soaker in the weather biz.
A slow sprawling low pressure system has dropped widespread rainfall to Minnesota and the Upper Midwest. The rainfall totals are impressive in most areas.

Look for a brief lull in the rain overnight into early Tuesday. The next weather system will move rapidly back into the region by Tuesday afternoon.
Rainfall totals look generally lighter with the next wave Wednesday into early Thursday. Forecast models are hinting at between .25" and .50" for much of the southern half of Minnesota.
Warming trend this weekend:
Look for a warming trend starting on Friday and lasting into next week. Temperatures should reach 70 by the weekend, and we have a shot at 80 next week. This could be the best fishing opener weekend weather in years. Highs near 70 and lows in the 40s and 50s and mild winds could make for nearly ideal opening weekend weather.
Leave the umbrellas at home and bring the sunscreen!
