WINTER WEATHER ADVISORY goes into effect tomorrow from 10am until 7am Wednesday. Traveling may be tricky during the day as a wintry mix of snow, sleet, freezing rain and rain is likely. It will be light and scattered for much of the day. Use caution if traveling during the hours of the advisory.
Cold front crossing the area will move slowly to our south but an area of low pressure will develop along it bringing a round of wintry precipitation. We should get through the morning commute with dry conditions and just some spotty snow showers mixed with sleet along the MD-PA line.
Lows will drop to around 30 degrees. Snow and sleet with transition to freezing rain and rain later in the day as temps warm in the upper levels. Eventually it turns to all rain with just pockets of freezing rain as surface temps warm above 32 degrees. Where temperatures do not warm above 32 is where we could still see a little freezing rain mix in. Temperatures will be very slow to warm up and we should see our high for the day of 35 as we head towards evening.
A coating snow and sleet followed by a glaze of freezing rain is possible but no significant accumulations are expected as of now.
We could see a few isolated showers Wednesday early but then skies will clear out as high pressure builds in. Highs will be milder in the upper 40’s despite limited sunshine during the day. More sunshine returns for Thursday but it will be cool with highs in the low to mid 40s. With a zonal pattern set up from Friday and beyond and several disturbances expected to ride in, each day could see hit or miss showers through Monday. Temperatures will remain in the 40s.
