.SYNOPSIS... High pressure will continue to bring warming temperatures and dry weather conditions to the region this week. A cold front moving southeastward out of Canada will usher in a cooler air mass for Friday and the upcoming weekend. However, measurable precipitation is generally not expected with this cold front, allowing drought conditions to persist across our region.
&&
.NEAR TERM /THROUGH WEDNESDAY/... As of 114 AM EDT Tuesday...The prolonged stretch of dry weather will continue across the region as surface high pressure and upper level ridging continue to remain the dominant weather feature. Another night with clear skies and radiational fog is ongoing with some patchy across the area. However, given the long detachment from precipitation, fog is not currently widespread but is still expected to develop in the climatologically favored areas as the night progresses.
Beyond sunrise today, another sunny and mainly clear sky is anticipated. A few mid to upper clouds are possible in southern Vermont from a decaying coastal low in the Mid-Atlantic, however, the remainder of the area should enjoy another bluebird sunny day. Temperatures will be in the upper 70s to near 80 with overnight lows tonight in the 50s for the valleys and 40s for the higher terrain. Humidity will remain low (30-40%) keeping the area on the comfortable side. Radiational cooling and fog look likely once again tonight with fog development in the favored locations. Wednesday will almost be a carbon copy of today temperature wise with values hovering around 80. Increasing mid to upper level cloud cover from the coastal low will overspread the region as the system subsides and broadens.
&&
.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY/... As of 114 AM EDT Tuesday...Ridging will persist through mid week into Thursday with cloud cover decreasing into Wednesday night. Some radiational cooling in northern New York looks to be favored Wednesday night, however, lingering cloud cover across Vermont may limit efficient radiational cooling. Fog remains possible in the favored locations Wednesday night, however, further detachment from precipitation will start to limit the spatial coverage of any fog in time.
High pressure will begin to break down Thursday as a trough begins to approach the area from the northwest. A brief warming trend ahead of the trough looks to take place with southerly to southwesterly flow Thursday. Highs will be in the low 80s in the Champlain Valley and upper 70s elsewhere. By Thursday afternoon, clouds will begin to increase from the west across northern New York.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... As of 222 AM EDT Tuesday...Very little rainfall is anticipated in the long term as drought conditions prevail acrs most of our region. A mostly dry cold frnt wl drop south from central Canada on Thurs night, with just a small pocket of schc pops from the NBM. Friday into Saturday wl feature moderately strong 925mb to 850mb caa on modest north/northwest winds of 5 to 15 knots. Temps mainly in the 60s to near 70F for Friday and Saturday with lows upper 20s to mid 40s, except near 50F in the CPV. Did note the MEXSLK had a 28 on Sat morning and 25 Sunday morning, so the potential for frost/freeze headlines are possible this coming weekend. 1030mb high pres builds directly overhead by Saturday, before slowly shifting eastward on Sunday into Monday with a return southerly flow of waa. Temps rebound back into the 70s by early next week with dry conditions prevailing. Lows warm back into the upper 30s to mid 50s by early next week. No significant or widespread wetting rainfall is anticipated over the next 7 days.
&&
.AVIATION /11Z TUESDAY THROUGH SATURDAY/... Through 12Z Wednesday...Its been a very challenging aviation forecast overnight with areas of shallow fog developing at several of our taf sites. This included MSS for several hours and briefly at BTV, while fog was slow to develop at SLK with prevailing VLIFR at MPV/EFK. Any lingering fog/IFR should lift by 13z at EFK/SLK and 1330z at MPV. Otherwise, VFR with light winds prevail thru 06z tonight. Fog development tonight will be tricky again with slightly stronger winds just off the surface with some increasing clouds expanding from south to north across our taf sites. These clouds and winds could limit fog development, so have just used tempo`s at SLK/MPV for now. Later shifts can fine tune IFR in future taf packages.
Outlook...
Wednesday: VFR. NO SIG WX. Wednesday Night: VFR. NO SIG WX. Thursday: VFR. NO SIG WX. Thursday Night: Mainly VFR, with areas MVFR possible. NO SIG WX. Friday: Mainly VFR, with local MVFR possible. NO SIG WX. Friday Night: VFR. NO SIG WX. Saturday: VFR. NO SIG WX.
