A warm front is approaching the Middle Atlantic states from the south. Consequently, temperatures will be on the rise as we move through the evening hours and into Monday. Highs on Sunday ranged from the low to mid 50s in the Annapolis area and will hold steady overnight. Rain showers with possible thundershowers can be expected toward midnight and continuing into the morning hours on Monday. Warm air from the south will surge into the area on Monday after the warm front moves to our north. As a result, afternoon highs may reach the lower to middle 70s under partial sunshine. The record high temperature for the date is 73 degrees in 1979 at Baltimore (BWI). The record is in jeopardy, especially if the sky begins to clear during the afternoon and a few hours of sunshine occurs. As we move through the week, a cold front will bring in much cooler air on Tuesday with highs about 20 degrees cooler than Monday’s highs. Even colder readings are expected on Wednesday as a coastal system develops and brings a round of significant winter precipitation to the Middle Atlantic states on Wednesday into early Thanksgiving morning. Highs on Wednesday will only be in the 30s. At this time, it looks like rain will be the predominant form of precipitation along the Delaware, Maryland, and Virginia coastline. Farther to the west, locations such as Washington, Annapolis, and Baltimore may experience a cold rain on Wednesday that gradually changes over to snow Wednesday evening as colder wraps around the center of low pressure. Some accumulation of snow is possible, but it is far too early to determine amounts, timing, or intensity as there are many variables that need to be analyzed. Those who are traveling into the area, or away from the area, should make plans accordingly and avoid travel north and west of Baltimore on Wednesday.
