National Weather Service Gray ME
929am EDT Monday Mar 25 2019

Synopsis: A cold front will move through the forecast area early this morning followed by high pressure building in from the north. This high pressure system will provide fair weather for many days before moving offshore at the end of the week.

Near Term - Until 6pm This Evening
930am Update...Forecast package in pretty good shape this morning with sunny skies prevailing across the region. Temperatures in a few places are rising a bit faster than expected. Will make a few small tweaks and bump temperatures up a degree or two in a few places. Otherwise, forecast will remain largely unchanged.

635am Update...Little change to the going forecast. Cloud shield in the wake of the cold front will move south of the forecast area in an hour or two as high pressure builds on in.

Previously... A cold front will continue to move southward and eventually out of our CWA early this morning. As of 2 am it was located along a KLEB-KLEW line and was aiding in an area of snow showers in the mountains. As the front progresses southward over the next few hours, the snow showers will end and skies will continue to clear from the north. By mid morning, sunny skies are expected over the entire forecast area. Temperatures will be cooler today as the Canadian high builds in, with highs in the 30s to lower 40s

Short Term - 6pm This Evening Through 6pm Tuesday
High pressure will continue to build in tonight. Clear skies are expected as a result, with cold temperatures. Low temperatures are expected to be in the single numbers and teens. Sunny skies expected Tuesday with highs mainly in the 30s

Long Term - Tuesday Night Through Sunday
Ensemble and deterministic model solutions are in decent agreement on the long wave pattern through the start of the upcoming weekend. A cool start to the extended period as the upper trough is in the process of lifting out. Otherwise...a split flow regime will be in place across the CONUS with the northern branch remaining largely to our north for the period...keeping the cold air and below normal temperatures bottled up to our north. For a change...we should see temperatures average near or above normal. In the dailies...high pressure builds east across the region for Wednesday and Thursday. A cold front will cross the area with a few rain and snow showers Thursday night into Friday. The front will return north as a warm front next weekend as low pressure tracks east along the boundary.

Marine Discussion
