Storms Return to Forecast; Cooler behind Front
5:40 p.m. Mon 21 August 2017

The partial solar eclipse came and went for Texoma, and during its passage the temperatures dropped two degrees – normally a very rare event at mid-day with full sun in August. Of course, the reduction in solar radiation was the cause. The eclipse ended at 2:38 p.m. local time and we enjoyed a sunny but very humid afternoon.

It will be a mostly clear and warm night with lows in the mid-70s; Tuesday will be another hot and humid one with highs in the low to mid 90s and Heat Indexes over 100. Showers and thunderstorms will form late afternoon along an advancing cold front; highest rain chances are tomorrow night into Wednesday morning.

Drier air will gradually filter in behind the front ending rain chances late week. The ECMWF and GFS models both develop a major hurricane off of the south Texas coast later this week; if this happens it will have an impact on our forecast so my confidence in the weekend numbers is not especially high at this point.

Here are the numbers:

Tonight: Mostly Clear…..Low mid-70s
Tuesday: 30% Thunderstorms afternoon…..Highs 93 to 96
Tuesday night: 70% Thunderstorms, heavy rainfall…..Low near 70
Wednesday: 40% Thunderstorms, not as hot…..Highs upper 80s
Thursday: 20% Showers….69/86
Friday: Mostly sunny…..68/87
Saturday: Mostly sunny…..70/88
Sunday: 40% Thunderstorms…..70/88
Monday: 20% Showers…..68/90
