Wind speeds were a little stronger than forecast overnight and the temperature hovered around 27 for several hours. We'll see a large diurnal temperature range today thanks to dry air, southerly winds, and a building upper level ridge. It's been awhile since we have been influenced by ridging aloft and because of it, we'll see temperatures 15-20 degrees warmer than the last couple of days. We should have abundant sunshine this afternoon so look for the high to be 58. With a new air mass in place, I may be going a little too low on the high and we could reach 60 today. I'm still reluctant to go too warm just in case any of the last remaining arctic air mass is still around.
Moisture will be increasing throughout the day as southerly winds begin to pump Gulf moisture into the area and approaching upper level disturbances will cause high clouds to increase after midnight. These two factors will keep us several degrees warmer overnight, but I still think we'll drop to 41. Clouds will continue to increase and thicken tomorrow as our next rain maker arrives. It will be even warmer with highs well into the 60s.
