…. April Ends on a Dry Note with No Rain in the Seven Day Forecast ….
On this Tuesday morning…. a cold front extends from northeast Mississippi and central Louisiana to just ashore on the Texas coast. Surface high pressure.. behind the front.. is over the northwestern USA. As a result of this surface weather pattern, our local surface winds are northerly.
In the upper levels of the atmosphere… a strong counterclockwise rotating trough, or line, of upper air low pressure extends southward from southeastern Iowa into the lower Mississippi Valley. As a return of this upper air wind pattern, the upper level winds over south central Texas and the Austin metro area about 18,000 feet above the ground, are westerly 75 to 85 mph.
A cold front has pushed southeast of the local area with a clear skies and cooler temperatures to prevail into the middle and latter part of the week.
Southerly surface winds will return with a corresponding increase of low level moisture by Friday and through the weekend into early next week. Clouds will increase a bit with the return of late night and early morning low cloudiness.
Unfortunately, I do not see rain chances for south central Texas over the next seven days.
Regarding my forecast, my local forecast confidence: My forecast confidence is high to very high today through the seven day forecast period.
Have a good Tuesday…
