Unsettled Skies this Week…
5:30 p.m. Monday 25 July 2016
Daytime heating, a weak upper disturbance and a boundary left over from storms last night helped to trigger a new round of scattered Monday storms in Texoma. Severe weather was not observed, but these did produce a lot of lightning, heavy rainfall, and a few gusts to about 40 mph.
Most of the night should be quiet; however, a stalled frontal boundary over central Oklahoma may fire more storms after midnight that would drift our way. So, I will keep a 20 percent chance of storms in the overnight forecast to account for this. Daytime heating and a very weak cap will make for more scattered storms Tuesday and Wednesday in the 30 percent range.
The upper high that was on top of us last week has shifted westward, leaving the steering flow out of the north and northwest this week. A mid-level trough passing through this flow on Thursday brings our highest chance of rain for the week. Lower rain chances may linger through Saturday as a hot moist atmosphere with only a weak cap bubbles out a few storms each afternoon.
Here are the numbers:
Tonight: 20% Storms, warm and humid…lows mid-70s
Tuesday: 30% Showers/storms…..Highs mid-90s
Wednesday: 30% Showers/storms …..75/96
Thursday: 50% Showers/storms …..75/92
Friday: 30% Showers/storms…..73/95
Saturday: 20% Showers/storms…..75/97
Sunday: 20% Showers/storms …..76/97
Monday: Mostly sunny…..76/98
