Most of our area could use a 2 to 4″ soaking of rain to get out of the current dry spell that most of us have experienced over the past 30 days. The image above (courtesy NOAA) shows 30 day rainfall departure from average across the Washington Region.
The areas that have received most of the rain this month have been mainly across upper Montgomery county, Baltimore City and its eastern suburbs and portions of north-central Virginia and southern Maryland.
Expect another hot Wednesday before a mainly dry cold front passes tomorrow evening. Thursday will feature another spectacular day with sunshine and low humidity. Then the humidity will make a come back for the weekend out ahead of our next cold front which should arrive (hopefully) during the peak heating on Sunday. If the front slides through during that time, it will be our best shot at some more widespread showers and thunderstorms.
