It will be partly cloudy and cool tonight with a 20% chance of thundershowers this evening. Low temperatures will range from the low-60's in Galveston to the upper-50's on the mainland. Expect northeast winds at 5-10 mph. Friday should bring sunny skies and cool temperatures. Highs will be in the mid-70's. Expect northerly winds at 10-15 mph. On Saturday, we should see mostly sunny skies and chilly conditions. Highs will be in the mid-60's. Winds will be from the northeast winds at 10-20 mph.
SYNOPSIS AND OUTLOOK:Somewhat cooler air has moved into southeast Texas behind a cold front. High pressure is building into the region. However, an upper-level disturbance moving across the Plains could set off a few showers this evening. A reinforcing shot of cool air will move in on Friday with the coolest weather of the season likely for Saturday, along with sunny skies.
At the surface, a cold front is moving slowly southeast from near the Big Bend, across South Texas and the northern Gulf of Mexico to the Atlantic. High pressure is ridging southwest from the Ohio Valley to Arkansas and East Texas. A weak front and upper-level short wave is pushing across the east-central Plains, while to the north another cold front is beginning to move south into South Dakota and Montana. Elsewhere, high pressure is over the Rockies while a cold front is moving towards Oregon and Washington from the Pacific.
At the upper-levels, we have a low pressure trough over the eastern half of the U.S. and a high pressure ridge over the western third of the country.
Cooler conditions will continue to work into Southeast Texas with a chance of thundershowers tonight and much cooler conditions by Friday and especially Saturday. Sunday and next week should see a gradual warm-up with rain chances increasing by mid-week.
The Tropical Atlantic Basin has settled down some over the past 24-hours, though we continue to monitor a 1009 MB low and upper-level trough northeast of the Virgin Islands (95-L). This disturbance is bringing squally weather and heavy rains to that region. The National Hurricane Center has lowered chances of development of this disturbance to 10% over the coming 48-hours and a 10% chance over the coming five days. Strong wind shear and a pool of dry air to the north and west continue to hamper this system.
Meanwhile, the remnants of former Tropical Storm Hanna linger along the coast of Honduras and Belize, but storm activity has diminished and re-development is not expected this time. Otherwise, conditions remain unfavorable overall for any development in the Tropical Atlantic Basin and tropical cyclone development is not currently anticipated.
