The extended outlook calls for sunshine on Wednesday with a high in the upper 20s. Clouds and sun on Thursday with evening snow showers. The low will be in the lower 20s and the high will be in the upper 30s. A chance of rain and/or snow showers on Friday with a low in the lower 30s and a high in the mid 40s. Clouds and sun on Saturday with a low around 35 and a high around 50. Mostly sunny on Sunday with a low around 35 and a high in the lower 50s.
As the sun begins to set on Chesapeake Bay, areas of mist and fog are being reported. Temperatures are quite mild to the south and east of Annapolis with 5 p.m. readings in the 50s and 60s near Ocean City, Salisbury, and Richmond. Meanwhile, to the north and west the mercury is struggling to break above the freezing mark. In places like Frederick, freezing mist has caused icy conditions all day. Despite the persistence of the cold across northern Maryland, the cold front approaching from the west will cause warmth to surge northward ahead of the frontal boundary so that temperatures may be as warm as the low to mid 50s by morning in the Annapolis area. Strikingly, by evening we may be in the upper 20s with a wind gusting from the northwest at 20 to 40 miles per hour! A few rain and/or snow showers may accompany the frontal passage on Monday, but no accumulation is expected. The main headline will be the tremendous cold that will send temperatures plunging to near zero by Tuesday morning. Locations right along the bay shore will probably stay in the single digits to around 10 degrees. Highs on Tuesday may stay in the teens with a wind chill below zero. Fortunately, the cold snap will be short-lived as the mercury recovers quickly into the 30s on Thursday and 40s by Friday. A storm system may bring rain or mixed precipitation to the area Thursday night into Friday. Right now, next weekend looks fair with highs in the 40s to lower 50s and overnight lows above freezing.
