UPDATE: 9:45 p.m.
I lowered tomorrow's highs by a few degrees based on the latest model trends and upstream temperatures; otherwise no changes. After the warm spell, it will feel quite chilly!
Have a great night - Steve
Cooler for the Weekend
5:15 p.m. Thu 23 February 2017
Record warmth and strong winds Thursday will be replaced by a cooler air mass overnight thanks to an advancing cold front. Temperatures on Friday will run 20 to 25 degrees cooler than they were today! It will be sunny and windy, but not to the degree it was today.
A big-time lack of moisture should limit the frontal passage to just a few clouds with no rain expected.
Surface high pressure builds in allowing for decreasing winds Friday night and a pretty good chance of frost or even a light freeze Saturday morning. Given the very early blooming of plants this year, tender vegetation should be protected.
After a sunny and cool Saturday and a chilly start to Sunday, we’re right back to spring-like weather with a chance of thunderstorms by Sunday night as an upper-level trough scoots by.
We get a quick warm-up on Tuesday ahead of a significant cold front which pushes temperatures downward for Wednesday and beyond. Moisture looks limited with the Tuesday system so I’m keeping rain chances at 20 percent for now. This will probably need to be adjusted one way or the other as we see how quickly Gulf flow resumes behind the weekend system.
Here are the numbers:
Tonight: Clear and windy, cooler late….Lows 44 north to 53 southeast
Friday: Sunny, windy, cooler…..Highs 55 north to 61 south
Saturday: Frost/freeze a.m., sunny and cool….32/54
Sunday: Partly cloudy, windy, 30% rain late, 60% Sunday night…..35/63
Monday: 60% Showers early, partly cloudy p.m.…..48/63
Tuesday: 20% Showers or storms…..44/75
Wednesday: Mostly sunny and windy…..41/58
Thursday: Sunny, frost a.m.…..35/60
