Forecasting Austin and South Central Texas Weather Since 1984

TK’s Weather Discussion….

Updated 845am CT – Wednesday / 25 June 2014

…. A Continued Unsettled Early Summer Weather Pattern ….
…. Rain and Thunderstorm Chances Continue Through the Seven Day Forecast ….

On this Wednesday morning…. a weakening stationary front is anchored to a surface low pressure area over northern Ohio and extends southwestward through middle Tennessee.. northern Mississippi and central Arkansas then westward into Oklahoma. Surface low pressure is located over western and southern New Mexico with a trough.. or line.. extending southward into northern Mexico. As a result of this surface weather pattern, our local surface winds are southerly.

In the upper levels of the atmosphere… the upper level high pressure area continues to be centered over northwestern Mexico with an upper level low pressure disturbance over central Texas. As a result of this pattern, the upper level winds over south central Texas and the Austin metro area, about 18,000 feet above the ground, are variable at 8 to 15 mph.

A moist and unstable air mass continues over our area. The upper level low pressure disturbance overhead is combining with low level moisture and daytime heating to maintain the more unstable weather pattern across our area.

At this point, based on the latest computer and manual NWS forecast guidance, I think the highest rain chances will be today into tomorrow.. mainly in the daytime hours.. with potential rainfall totals of 1/2 to 1 inch possible. Severe weather (i.e., hail, damaging winds) is not expected.

By Friday and through the weekend and into early next week, late night and early morning low clouds will continue to dominate with a partly cloudy sky otherwise. Daytime heating will combine with low level atmospheric moisture and atmospheric instability to keep slim rain chances in the forecast.

Overall, over the next seven days, I expect our temperatures to be close or perhaps to degree or two below seasonal averages.

Regarding my forecast, my local forecast confidence: My forecast confidence is medium to high over the next day or so (with rain and thunderstorm timing and chances as well as rainfall amounts being the issues). My forecast confidence rises back to medium to high by Friday through next weekend and into early next week.

Have a good Wednesday…
