Abundant sunshine is expected once again today, although we will start to see some increasing high level clouds by later this afternoon. High temperatures this afternoon will climb to around 60 degrees across much of the region away from the coast. Dry weather is expected to continue tonight as the mid and upper level ridge begins to break down in advance of a weak warm front. Expect mainly clear skies this evening to be followed by increasing high and mid level clouds tonight. Lows tonight will range from the mid to upper 30s across the region. && .SHORT TERM /SUNDAY THROUGH MONDAY/... Sunday morning likely to see area between departing hipres and approaching cold front at the sfc. Aloft upr ridge axis will be centered over the region and should slow progression of any showers in the morning before approaching wave begins to flatten the ridge and showers move into the region by 18z, from about the Baxter Region northward. Southerly winds will bring warm temps for all but the immediate coast with inland areas climbing into the 60s and coastal regions stuck in the mid-40s. Front will approach fm the northwest Sunday evening with fropa occurring across the north after 06z, central areas by 09z and offshore by 12z. Spotty showers are expected with boundary, though most areas should remain dry. Temps will drop into the 30s over the North Woods by morning but remain in the l/m 40s over Downeast. Dry Canadian high pressure will begin to build in on Monday with gusty nw winds expected. Have undercut dwpts on Monday afternoon given the dry airmass and have blended in the 10th percentile of the NBM with CONSMOS for the afternoon and evening hours. Min relative humidity values Monday afternoon will drop to around 35% but may be need to lower these in the coming days. Highs across the north will be near normal with southern areas above normal in offshore flow. Ridge axis will be square over the region Monday night keeping us precip-free during the overnight hours. Given dry airmass and mostly clear skies initially temps should be able to drop to near freezing across the north. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... Middle of the week should remain mainly precip-free with the exception of Tuesday night into Wednesday morning as potential sfc low slides off of the srn New England coast. Operational runs of EC and CMC indicate this potential impacting Downeast with rain while GFS is too strong with sfc high to move much in the way of measurable rainfall onto the coast. Ensemble runs at both the sfc and aloft wash out any significant features and have lowered pops for Tuesday and Wednesday. Wednesday night will see upr ridge crest over the area with next in a series of subtle s/wvs drifting acrs the area thru the end of the week. Temps on Thu and Fri will climb into the 60s for inland areas && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... NEAR TERM: VFR through tonight.
