WEATHER BLOG: Cooler Temps, Chance Of Rain By This Weekend

Our local weather will feature a rather nice end to our week, with mostly sunny skies and warm late August temperatures.

By Saturday, an area of low pressure is expected to bring plenty of clouds and cooler temperatures along with the chance of some showers. It appears the bulk of the rain will occur on the eastern side of Maryland and probably very little west of the Blue Ridge Mountains. Temps will have trouble getting much higher than 80 on Saturday, but will warm up again by early next week.

In the tropics, Tropical Storm Isaac was located about 180 miles SSW of San Juan, Puerto Rico and moving WNW at around 16 mph with minimal tropical storm winds of 40 mph. Heavy rains are the main threat for Puerto Rico Thursday night but Isaac is expected to get stronger Friday and may become a Category 1 hurricane as it moves closer to Haiti and eastern Cuba later Friday and on Saturday. It will then be affected by the mountains of Cuba and lose a lot of its punch but still cause life threatening rains in those areas. Most of the current models have pushed Isaac a bit further to the west of SW Florida by Monday and may eventually affect parts of Alabama and the Florida Panhandle by Tuesday. We will continue to update and track Isaac and its possible effect on the United States all weekend and next week.
