A cool start, but milder to finish to the week

A blocking pattern continue to keep and upper-level trough over the mid-Atlantic and Northeast. This is keeping our temperatures below average as cold air from Canada is allowed to flow Southward. Our morning low today was 23 and the high was only 52. We should be in the upper 50s this time of year. The blocking pattern begins to break down and the trough moves out on Tuesday. This will begin to allow milder air to move in for Wednesday. Highs return to above average in the 60s from Wednesday into the weekend, possibly some 70's on Friday. There is a very slight chance for a shower on Thursday as a weak front get close to the area from the North. The best chance for showers look to arrive Saturday afternoon and Saturday night.
