The extended forecast calls for a chance of rain showers on Friday with a low around 45 and a high near 60. Clouds and sun on Saturday with low around 45 and a high near 50. Clouds and sun on Sunday with a low in the upper 30s and a high in the upper 40s. Mostly sunny on Monday with a low around 30 and a high in the mid 40s.
Sunshine was plentiful in the bay area today with a frigid start as temperatures dropped into the upper 10s to mid 20s, and afternoon highs struggled to break above the freezing point. Meanwhile, a weak weather system to our west will impact our region with snow and possible slick travel conditions during the Tuesday morning commute. A Winter Weather Advisory is in effect for the Annapolis area tonight. High pressure this evening will give way to a weak center of low pressure that will cross the Appalachian Mountains and move across southern Pennsylvania. As a result, light snow is expected to develop and move through the region overnight, probably between 2 a.m. and 5 a.m. Temperatures will be cold enough to support all snow. About one inch of accumulation is expected. Across southern Maryland, temperatures will be a bit warmer so that precipitation may fall in the form of mixed rain and snow, or just rain showers. After a few morning flurries, the sun will break through the clouds and temperatures will rise into the 40s on a southerly wind. The remainder of the week will feature mild conditions. A weak system may bring some rain showers on Wednesday, but afternoon highs will reach into the 50s. Maximum readings are expected to climb into the 50s again on Thursday, and perhaps even low 60s on Friday as warm air rushes north ahead of an advancing cold front. The frontal passage may produce widespread rain showers during the day on Friday.
