Severe Thunderstorm Watch for Baltimore, Washington, Annapolis

Brian's exclusive forecast for Baltimore and Annapolis:

The National Weather Service in Sterling VA has issued a Severe Thunderstorm Watch for locations in central Maryland including Baltimore, Annapolis, and Washington DC until 10 p.m. this evening. Thunderstorms will continue to develop across the region this afternoon and evening. Some storms may produce heavy rain, gusty winds, hail, dangerous lightning, and localized flooding.

Weather Summary

A line of powerful thunderstorms extending from south-central Pennsylvania into northern Virginia pummeled the Baltimore and Washington areas last evening with strong winds and heavy rain. Today's weather will be slightly cooler than yesterday with highs in the upper 80s instead of the mid 90s. However, it will remain humid and with a cold front approaching from the Great Lakes region there will be enough instability to allow for scattered thunderstorms this afternoon and evening. Thursday's weather will be much the same as the front continues to push through the region. Friday will be sunny and less humid as a northerly breeze overspreads the area in the wake of the frontal passage. However, the front is expected to lift back northward as a warm front on Saturday and ushering in more humid conditions for the weekend with highs in the upper 80s on Saturday and Sunday. There is a slight chance of a thunderstorm over the weekend as well.
