Well, it's been 12 days since we've had measurable rain at BWI, and we will break that trend tonight. While these totals will not be overwhelming, and measurable rain is appreciated. Most locations will pick up roughly a quarter to a half inch of rain, with isolated locations picking up slightly higher amounts. Most of the moisture will exit overnight ,but on the backside of the low pressure system will slide through on Saturday. Coverage will be minimum, and should just result in a few sprinkles, but we cannot rule out isolated snowflakes in the western part of the state or areas at higher elevations.
Temperatures behind the front will be slightly cooler. On Saturday looks like we'll see some lingering cloud cover as the system makes it way eastward, but highs struggle to reach the mid 40s. By Sunday, we'll see more sunshine, unfortunately the winds will be a bit elevated, so it will feel a little cooler-- wind chills hanging out in the upper 30s during the afternoon.
After that we have a nice stretch of dry weather, with rain chances returning next Thursday.
