From summer to a return of more late fall type weather. We were near 90 for a couple of days...and now highs may struggle to get to 60 or so for a couple of days and another chilly for the season airmass gets ready to move into the area. You can see the chill on the 2PM surface map out to the west...



The chillier air across the western plains will arrive towards tomorrow morning. As a result highs tomorrow with lots of clouds expected are going to be in the 55-60 range and perhaps even chillier in the PM hours with showers in the area. The moisture may have a tough time getting scoured out after it arrives. So while some sun is expected, clouds may be the predominate weather over the weekend and with the chillier air aloft moving through the region, and also at the surface, highs are going to struggle all weekend.

From Monday on next week...the weather may be VERY nice for a few days, perhaps still a bit below average, but MON-THU could be real gems with highs in the 60s/70s and lows in the 40s/50s. At this point no significant rainfall,a side from whatever happens tomorrow is expected for awhile.

Meanwhile for the rest of the day today, our storm chances seem pretty small at this point. Can't rule something out but the higher chances appear to be closer to the surface low. The SPC has issued a Tornado Watch for parts of N KS and S NE for the rest of the afternoon and early evening...


Take a look at the radar loop from the Plains states to get an idea where the storms are going to move...basically they'll be swirling around the upper level low which is spinning across the Plains states. Here is a link to the Radar Loop

Now look at the visible satellite picture with clouds rapidly moving from S>N up the State Line into the metro area....


Along the back end of that cloud cover from Topeka southwards is an area that will need to be watched. There is some weak convergence there and some of our extremely short range models are showing the potential for at least some scattered convection to boil up.

Have a great Friday and I'll update the blog again this weekend.
