Area Forecast Discussion|
National Weather Service Caribou ME
612am EDT Fri July 3 2020
High pressure will build across the area today. A cold front will begin to cross northern areas Saturday then cross the remainder of the region Sunday. High pressure will build across the region later Monday into Tuesday.
.NEAR TERM Through Tonight
6:12 am update: Satellite pictures, observations, and web cams show that the low clouds have pushed north overnight and now cover most of the FA. There are some breaks in the clouds across parts of northern Piscataquis County and northwest Aroostook County. Made some adjustments to the sky grids for this morning to increase the cloud cover. Still expect that the clouds will begin to erode with more breaks of sunshine by late this morning into early this afternoon. The clouds may hold for much of the day along the coast. Otherwise, the only change at this time was to load the past few hours of observed data.
Previous discussion: A weak ridge of high pressure across northern Maine will slowly move off into the Maritimes today. The cold front that crossed the area yesterday will push south of New England today. A weak surface trough is expected to drop south and into northern Maine this evening.
Today will feature intervals of clouds and some sunshine and it will be noticeably less humid. Temperatures will be seasonable with highs in the 70s, except low to mid 60s along the immediate coast. As the surface trough drops south into far northern Maine can't entirely rule out an isolated -shra/thunderstorms with rain late this afternoon, and most of the guidance now has some showers late in the day will add an isolated late day shower into this evening across the Saint John Valley. Expect a partly cloudy night with seasonable lows in the 50s. Along the coast and into the Downeast region there will likely be some late night low clouds and patchy fog.
Short Term - Saturday Through Sunday
H5 trough remains across the forecast area through the short term with west to northwest flow aloft persisting Saturday thru Sunday. A weak upper disturbance/surface trough will cross the region later Saturday. Moisture will be limited in the northwest flow aloft, so will only carry slight chance to low chance pops, mainly across north central portions of the region, where steepest lapse rates will exist. With little in the way of surface based CAPE, decided to omit mention of thunder. Otherwise, expect partly to mostly sunny skies on Saturday. Highs on Saturday are expected to range from the lower 80s across the north and lower to mid 70 Downeast. Saturday night will feature partly cloudy and dry weather conditions. Light southerly flow may lead to some low stratus and areas of fog toward the Downeast coast and Penobscot River Valley, with SREF probabilities hinting at this as well. Sunday is shaping up as a potentially interesting weather day. An even stronger upper disturbance and associated cold front will cross the region during the afternoon. Expect showers and thunderstorms Sunday afternoon. 0 to 6 km shear increases to 35 to 40 kt but surface based CAPE looks limited. A few gusty showers or a thunderstorm cant be totally ruled out though with the passage of the front.
Long Term - Sunday Night Through Thursday
Temperatures will gradually moderate through the long term period of the forecast. Upper level ridging will build in for the early part of the upcoming week. This will bring fair and mainly dry weather Monday and Tuesday. A warm front will lift up across the area during mid week with increasing instability and the chance for showers and thunderstorms. Temperatures are expected to warm to well above normal levels by later next week.
Near Term: The wind and seas will remain below small craft advisory levels through tonight with seas 2 to 4 feet on the coastal waters and around 2 ft on the intra-coastal waters. A northeast wind may locally gust to 20 knots at times today with the wind to turn into the east and diminish to 10 knots or less tonight. Patchy fog at times, especially this morning and again late tonight.
Short Term: Winds/seas will remain below SCA (Small Craft Advisory) levels through most of the early to mid week period. Visibility will be occasionally lowered to 1 to 3 NM in areas of fog.
