SYNOPSIS AND OUTLOOK
Fairly light wind, partly cloudy skies and seasonably hot temperatures will prevail through tomorrow. High pressure to our west will slowly build east. Meanwhile, ample Gulf moisture and daytime heating will keep a chance of widely scattered thundershowers in our forecast through Sunday.
This morning we continue to see an elongated and semi-stationary frontal boundary extending southeast from Idaho to a lows in southeast Colorado, Virginia and southeast Pennsylvania. The front then extends northeast along the East Coast to eastern Canada. Thunderstorms are expected along the frontal boundary over the Plains.
At the upper-levels, we continue to see a mostly zonal west to east flow with a broad, weak low pressure trough over New England, the Great Lakes and the Mississippi River region. Meanwhile, the high pressure ridge over the Desert Southwest is beginning to strengthen and expand over the region with high pressure extending from New Mexico to Oregon.
Drier and hotter conditions will return as we move into the weekend and high pressure re-asserts itself over our area. A chance of scattered thundershowers will remain through the weekend with drier conditions setting in by Monday and Tuesday. Looking further down the road, rain chances may increase again late next week as an upper-level low develops over the Gulf of Mexico. Overall, look for fairly typical summer weather for the next few days.
A tropical wave located about 1200 miles east of the
Leeward Islands is moving westward at about 30 mph. The potential system is being given a 20% chance of development over the coming 48-hours and a 30% chance through the next 5 days as it moves west at 25-mph. A second tropical wave accompanied by a low pressure system about 300 miles south-southeast of Cabo Verde is being given a 40% chance for development over the coming 48-hours and a 50% chance over the next 5 days. Elsewhere, tropical storm development is not expected in the Tropical Atlantic Basin at this time.
