SYNOPSIS A weak mid level disturbance will bring light rain and snow to a good portion of the region today with minimal accumulations expected, mainly in the higher terrain. Our active weather pattern will continue with a strong cold front arriving Friday bringing a few additional rain and snow showers followed by cooler temperatures for the coming weekend.

NEAR TERM UNTIL 6 PM THIS EVENING 645 AM Update... Little change to the going forecast as we're on track based on latest trends in observations and mesoscale model data. Did back off on PoPs for today across a good portion of ME based on some drying to the northeast and forcing for ascent remaining a bit further southwest, mainly over southwestern NH. Otherwise, very little change other than some minor adjustments here and there.

Previously...

An upper level trough and attendant SFC convergence zone will gradually move eastward across the forecast area. This will allow for enough ascent for light precipitation to fall much of the day, but especially this afternoon across New Hampshire.

Much of the Maine portion of the forecast area will be drier during the day today as the area of best SFC convergence will remain across NH. However, late this afternoon and early this evening there may be a burst of light precipitation on the coastal plain of Maine as the departing mid level low aids in the generation of a brief period of frontogenesis.

Precipitation type today will be mainly rain at lower elevations with some snowflakes mixed in at times during periods of briefly stronger ascent. At higher elevations, mainly from the Monadnocks northward into the White Mountains an inch or two of snow may fall today, mainly above 800 feet or so. However, a coating is possible at lower elevations.

Temperatures will be above freezing today in most locations except hovering around 32 degrees in elevated terrain.

SHORT TERM 6 PM THIS EVENING THROUGH 6 PM THURSDAY Low pressure moves away tonight with any light rain or snow ending during the evening. Gradual clearing is expected to occur after midnight. Thursday will finally feature mostly sunny skies with highs in the 40s.

LONG TERM THURSDAY NIGHT THROUGH TUESDAY The extended looks like a busy end to this week followed by a quiet start to the next.

Fri remains on track for a strong cold frontal passage. Ahead of the front Thu night I will continue to show a non-diurnal trend in temps within the Sly flow. The low level boundary and upper level trof are both set to cross the region during the latter half of the day. Best chances for precip will be in the mtns... where there will be a combination of frontal precip and upslope snow showers. Farther S chances for precip will drop off quickly... and some areas may see little if any precip at all.

The majority of sensible wx will be CAA and gusty winds behind the front.

Importantly the front will begin to stall off the coast as the main S WV trof lifts towards Newfoundland. This low level baroclinic zone will be a focus for low pressure amplification as the next S WV trof approaches from the central CONUS. It remains a low confidence track forecast at this range... but occasional deterministic runs and several ensemble members support a system close enough to the forecast area to bring widespread precip. With 925 mb temps forecast to be around 0C to +1C that brings snow into play for many areas. Given that ensemble guidance is showing sensitivity towards a S WV trof currently S of the Aleutian Islands... we have a couple of days until we are likely to see some consensus on track and timing.

With that in mind I have stayed close to the multi-model blend.

I did however bump PoP up anticipating a bit of a NW trend less progressive bias to forecasts. That also meant that I increased cloud cover slightly and lowered daytime temps a couple of degrees with expected precip falling Sun.

AVIATION 12Z WEDNESDAY THROUGH SUNDAY Short Term...

Mainly IFR conditions expected at most terminals today as light rain or snow falls (snow in the interior, mainly above 800 ft in elevation). The low level moisture begins to get scoured out tonight as low pressure moves away to the east. Therefore, gradually improving conditions are expected after midnight tonight.VFR all areas late tonight and Thursday.

Long Term... Cold front approaches Fri with clouds gradually lowering thru the day. OverallVFR should prevail until the frontal boundary is on the doorstep. Some initial SHSN will quickly give way to SHRA and perhaps some mixed precip across interior areas. Widespread MVFR expected with areas of IFR... especially in any SHSN. The column will gradually cool again but likely not until after precip has ended at all terminals but HIE. At HIE continued upslope SHSN will keep the threat for local IFR or lower conditions into Fri night.VFR returns Sat.

MARINE Short Term...

Developing low pressure well offshore will cause northerly winds to strengthen over the waters with SCA conditions through tonight. Winds and seas gradually subside during the day on Thursday.

Long Term... A strong cold front will cross the waters during the latter half of Fri. CAA will promote strong wind gusts... especially outside of the bays... beginning Fri evening and continuing into Sat morning. Gale force gusts are possible on the outer waters... with strong SCAs likely in the bays. Winds and seas will gradually diminish thru Sat... but we will have to watch for a potential follow up system Sun that may prolong SCA headlines... or possibly even gales if system trends stronger.

TIDES COASTAL FLOODING Surge guidance suggesting that the Wednesday PM tide cycle may see tidal levels reach action stage. Can't rule out some splashover... although developing offshore flow will likely preclude any significant impacts. Will issue a coastal flood statement for Coastal York County to the seacoast for splashover awareness today.

GYX WATCHES WARNINGS ADVISORIES ME... None.

NH... None.

MARINE... Small Craft Advisory until 4 PM EST Thursday for ANZ150-152- 154.
