Temps moderate but with all the clouds...highs likely do not get out of the 50s (will maintain l60s far S for now). Cold Front passes through Wed...and with deeper mixing and WNW flow in low levels...should see some breaks in the clouds and a warm day with highs at least in the 60s. Showers will be most likely across the E and SE where drier air is slower to arrive. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... A series of low pressure systems will lift northeast from the Southern Plains during the long term period.

The precipitation ends from southwest to northeast late Friday and Friday evening.

There is a good chance for showers in the Mid Atlantic States by Sunday afternoon which continue into Monday. Kept POPs no higher than 40 to 50 percent due to a lack of confidence on days 6 and 7.
