Chilly Night...

Last night the low got down to 41 degrees at GTR...  Honestly I was a little surprised it went below 42 because of the moisture in the ground...  It was still fairly close though...  Tonight will be a perfect night for radiational cooling...  Calm winds and clear skies should allow us to drop near 40 degrees tonight...  The official NWS forecast is for a low of 42 degrees but I feel with basically no moisture left from Thursday's night/Friday's morning rain event the low will at least hit 40 degrees...  If we got to 41 last night I really don't see any reason why we shouldn't get a few degrees cooler tonight...  

The NWS weather service is calling for a high tomorrow of 77 degrees...  I think that's going to be tough to get to because we will start out cooler than predicted...  I would say 75 is more likely...  Today we only got to 66/67 degrees due to the fact we started out about 3 degrees cooler than originally thought...  Plus the air mass in general is verifying a little colder...  Fall is definitely here as the rest of the week looks fairly chilly...  A cold front with basically no moisture will move across our region Sunday night...  This will keep highs in the lower 60's Monday and  Tuesday...  We will have to watch for our first freeze of the season on Tuesday night...  Even the NWS is going 31 for Tuesday night...  Regardless of the freeze, Fall as arrived for us in the Deep South!!!
