Synopsis: A low pressure system over north Texas will move towards the southeast while drier air pushes down from the northwest (in the mid to upper levels). Airflow will begin to push out of the south (Gulf) on Friday but will bring a rather shallow layer of moisture into the area while that dry air out of the northwest continues to keep the moisture limited across South Texas through Friday night. Don’t rule out the low in North Texas sending some moisture down on Friday and combining with the sun heating up the atmosphere and triggering a scattered shower or two Friday afternoon in the Crossroads. Only 10 percent chances of rain for the northwestern portion of the viewing area while rain chances increase over the coast by early Saturday morning. The upper levels should stay on the dry side while the low-level surface winds bring in some Gulf moisture. This moisture could allow for some patchy fog overnight on Friday into Saturday morning. Saturday through Sunday a trough in the northwest Gulf of Mexico will be accompanied by a low-pressure system over Southeast Texas. The increasing moisture and these two features will increase rain chances to 20-30 percent over the weekend. The trough will move off to the northeast on Monday while a trough in the northern High Plains starts to move in from the west. Some rotation/spinning in the upper levels combined with this trough and moisture could bring scattered showers to the area on Monday as well. This trough in the Plains will extend from the Great Lakes down to Texas Tuesday and Wednesday that will push a cold front into the northern portion of the viewing area. As the cold front pushes through Tuesday night and all the way through on Wednesday, then some showers can start up. High pressure and drier air will push in behind the cold front, thus diminishing rain chances Wednesday night into Thursday. There is a chance that the cold front stays a tad to the north of the viewing area. Temperatures will be seasonal through Tuesday (Heat Indices from 105-109 degrees with Tuesday the hottest), but the cold front could drop temperatures several degrees below average after Tuesday.
Tropics: Nicholas is down to 15 mph and continues to weaken. There is a storm developing 250 miles east of Norfolk, VA and has an 80 percent chance of turning into a Tropical Depression and then into a Tropical Storm overnight, but the storm is headed off to the northeast (away from landfall). There is storm development between the Lesser Antilles and Cabo Verde Islands. This storm is moving northwest and could be near the Leeward Islands Monday or Tuesday with an 80 percent chance of further development. As the storm makes its way into the Southwestern Atlantic by the middle of the week then conditions become less conducive (strong upper-level winds) for strengthening. Last, a storm about 200 miles southeast of the Cabo Verde Islands will move west northwest with about a 20 percent chance of further storm development through the weekend. Then the storm will move into cooler waters and more upper-level winds that could start to diminish the development of this system.
