Area Forecast Discussion|
National Weather Service Caribou ME
705am EDT Sunday September 22 2019
High pressure will move south of the region today and tonight. Low pressure will approach Monday and slowly cross northern Maine through Wednesday morning. High pressure will build over the area Wednesday evening. A cold front will approach on Thursday.
.NEAR TERM Through Tonight
705 am Fog is sneaking up the vly toward Houlton as of 11z but no fog has dvlperiod across the north so hv rmvd fm these areas with fog lingering for the next hr before dissipating. Expect that mosunny skies will give way to increasing mid and high clouds fm nw to se as the day goes on but this will do little to prevent temp rise into the u70s/l80s over inland locations this afternoon.
Prev discussion blo... 1024mb surface high centered over West Virginia with ridge axis up to the northeast and thru the heart of the CWA. Winds are currently calm at most locations and with only thin cirrus over most of the area, temps are dipping into the 40s across the north. Deeper vlys of northwest Aroostook are currently as low as the u30s and believe these areas hv reached their lowest point for the mrng. Patchy fog has been hit or miss across the region this morning but hv not rmvd potential as microphysics satellite loop is showing dvlpmnt in the past hr.
Mostly sunny skies can be expected this morning before mid-high clods appch fm the west in advance of wv ejecting fm the northern Plains. H9 temps soar to nr +20C over cntrl sections of the area this afternoon and hv gone with lwr 80s over a good portion of the region for highs this afternoon. Onshore flow will keep coast and outer island in the u60s/nr 70 for highs tda but warm day expected rmndr of the area, approx 15 degrees above normal for this last day of summer.
Frontal bndry located fm southern Canada into the northern Plains wl slowly appch the state tonight. Surface low mvs northeast out of the Plains along the bndry and effectively stalls front just north of the international border thru the end of the pd. Showers may mv into the St. John Vly this evening and generally creep south through the ovrngt pd. Given the predicted cld cvr hv gone with mins in the l/m 60s for tonight to the north of Bangor, which may rival record high mins for Sept 23rd.
Short Term - Monday Through Tuesday Night
Rain showers will be focused in the north through Monday morning before low pressure begins to ride NE along the trough across Quebec. This will bring chance of showers further south through the afternoon hours into Downeast. Southern stream moisture will add to rain chances with PWATs (Precipitable Waters) rising above 1.5 inches. Along the coast through the evening and overnight, the low begins to become more vertically stacked and cut off. Portions of Downeast will be the warm spot for the day as SW flow intensifies between exiting high pressure and approaching trough. As a result, some elevated instability could bring an isolated thunderstorm. Much lift and forcing will be missing, and don’t expect more than a few rumbles mid-afternoon.
Trough continues to cross overnight taking on a neutral tilt. This will trend negative with divergence aloft along the ME/New Brunswick border Tuesday as surface low crosses over central Maine. Expect dry air to infiltrate on southern side of the low which would hamper shower chances there during morn/afternoon. However, additional forcing ahead and to north of the low’s track can take advantage of the moist environment, sharper forcing, increased instability, and 40kts of 0-6km shear. Given timing and location differences, have a wider area of isolated thunder chances for Tuesday afternoon, mostly Downeast to just south of a PQI/Clayton Lake line. These thundershowers could be deeper and bring more moderate or heavy rain at times, but haven’t added any enhanced wording at this time. Overnight, the low will continue to travel NE, with some lingering wrap around showers possible for northern half of the CWA.
Long Term - Wednesday Through Saturday
Some moisture still lingering across the north Wednesday as low is slow to exit fully into the Canadian Maritimes. High pressure will quickly nose in Wednesday night with a brief dry break before next chance of showers Thursday. A cold front will approach from west with bulk of moisture rounding the top of a surface high pressure across the Ohio Valley. Guidance agreeing that this should track across the region quickly as a large upper level jet aligns along the northern tier of states and US/Can border. Aforementioned high will continue towards east coast with FA entering a more NW dry flow regime towards end of week and early weekend. Temperatures during this time will return towards normal with highs in the 60s and overnight lows in the mid to upper 40s across the north, and around 50 Downeast.
Near Term: Winds will likely remain just below 25kts tonight with stable inversion present over the waters. Seas will rise to near 5ft tonight in southeasterly swell but confidence is not high enough to issue SCA. Visibilities will be reduced in patchy fog over the waters tonight.
Short Term: SCA (Small Craft Advisory) for hazardous seas may be needed Monday through Tuesday as waves could build to around 5 or 6 feet. Winds look to remain below 25kts given stable layer at surface. Waves go down, but remain 3 to 4 ft Wednesday and Thursday.
