The hour of sleep is lost, but the fact that Winter's grip will soon subside, is not. Still lots of snow to melt, and for that, we need the help of the sun. Sunshine is most abundant away from the coastline today and that restarts the snowmelt process we had yesterday. Before that process restarts, be careful of slick spots this morning on driveways, sidewalks, and secondary roads as black ice formed overnight. After 10:00AM, that should become less of a problem as temps rise above freezing.
Yesterday, we sure had an interesting temperature pattern with highs in the upper 30s at the coast to the mid 50s outside 495! The reason for that was the onshore wind. Water temps are only running in the mid 30s to lower 40s. Giving that the overall pattern doesn't look much different today, we may indeed see a similar temperature pattern this afternoon.
Temps warm-up even more Monday and Tuesday, and that means 50s for many! Monday still features mid to upper 40s at the immediate coast, but warm enough to melt more snow. Tuesday brings us rain... and it WILL be rain this time. Depending on how the evolution of a wave of low pressure forms along this front, we could wring out at least an inch of rain. While that wouldn't cause significant river flooding, we may see swollen streams from snowmelt and rain, and I certainly can see us dealing with big puddles/ponding on the roads for the Tuesday evening commute.
Wednesday is a transition day. We'll near 50 by mid-day, but that active west wind advects in cold air late in the day and by Thursday morning, you'll feel the difference. A colder pattern is where we stay into the weekend.
