SHORT-TERM OUTLOOK:High pressure aloft keep plenty of sunshine and hot temperatures around, though we will see some clouds and a chance of scattered thundershowers as weak upper-level low pressure persists over the southern Gulf of Mexico.
NATIONAL OUTLOOK:This morning, an active cold front will set off thunderstorms over the Texas Panhandle and the Great Lakes. The front is moving slowly southeast from a low east of El Paso to a low over southern Minnesota. The front then extends east from that later low across the southern Great Lakes and Mid-Atlantic region to the Atlantic. Elsewhere, Gert is located in the Atlantic off the East Coast, low pressure is seen over North Carolina. Finally, high pressure continues over Arizona and western Canada.
At the Upper-Levels, we seeing a slightly more amplified flow. While high pressure prevails from Texas to much of the Southeastern U.S., we find a low pressure center over far eastern Canada. Weak low pressure troughs are also seen over the northern and central Plains and the far southwest from Nevada to Southern California.
Typical summer conditions will continue as the upper-level high pressure ridge continues over Texas. A slight chance of rain will prevail through tomorrow as a weak upper-level low pressure is found over the southern Gulf of Mexico. However, the general pattern supports basically hot, dry conditions through the weekend. A trough drifting west in the Gulf of Mexico may bring a slightly enhanced change of showers early next week.
Hurricane Gert is located 350 miles south of Cape Race, Newfoundland. At 5 am, EDT, Gert was centered near 41.7 N and 54.0 W. Sustained winds were 100-mph and pressure was 968 MB (28.59"). Gert was moving east-northeast at 39-mph. Meanwhile, a disturbance 550 miles east of the Lesser Antilles has become better developed and is given a 90% chance for developing over the coming 5 days. Further east, a disturbance midway between Africa and the Lesser Antilles is given a 60% chance of developing over the coming 5 days and another south of the Cabo Verde Islands is given a 40% chance. Otherwise, tropical development is not expected at this time.
