.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 NIGHT/... As of 214 PM 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, with just a few high clouds streaming into southern portions of the forecast area. Another night with clear skies and some radiational fog is expected with the high continuing to crest overhead. With the lack of moisture, fog development is not expected to be as widespread as the previous night, with the best chances for fog east of the Green Mountains and along the Connecticut River Valley. Low temperatures will once again drop in the 40s and 50s.
Tomorrow will feature nearly identical weather to today, with seasonably warm temperatures in the 70s to lower 80s. Some high and mid level cloud cover associated with a decaying coastal low in the Mid-Atlantic will gradually overspread the region tomorrow,however dry weather will continue to persist. Overnight lows will be milder compared to the last few nights, with temperatures in the mid 40s to upper 50s expected, with almost 60 expected near Lake Champlain.
&&
.SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/... As of 214 PM EDT Tuesday...High pressure will begin to break down Thursday, with southerly flow across the region bringing another day of warmer temperatures. High will climb into the upper 70s across the area, with lower 80s expected in the broader valleys. A weak cold front will approach the region Thursday night, with little to no moisture associated with it. Some slight chances for showers will be possible, but any precipitation actually reaching the surface will be nonexistent or negligible, with drought conditions persisting across the region. Temperatures overnight will generally drop into the 40s and low 50s areawide.
&&
.LONG TERM /FRIDAY THROUGH TUESDAY/... As of 158 PM EDT Tuesday...Post frontal cold air advection is favored to maximize early Friday with northerly flow and gusts 15 to 25 mph. Strongest gusts will be in the Champlain Valley and on ridges. While there will be marginal fire weather concerns in very localized spots given ongoing drought, there are still leaves on trees tempering any stronger concerns at this time. Widespread frost will be possible outside of the Champlain Valley Friday night/Saturday morning as winds decrease with high pressure centering overhead again. Model output statistical guidance continues to point to lows around freezing for the Adirondacks and portions of northeastern Vermont with mid 30s for most locations and upper 30s to low 40s in the Champlain Valley. There are some indications that the pattern could begin to shift early next week, but will refrain from getting too hopeful for meaningful rainfall. A system could drag along the northern edge of the ridge bringing some showers as early as Monday. It remains to be see, however, if the ridge will hold stronger and shunt these chances more northward.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/... Through 18Z Wednesday...Main forecast challenge will again be related to fog chances overnight. There will be a slight increase in winds aloft as well as a period of high clouds for most terminals overnight. As such, the best chances of fog will be at MPV/SLK with lower chances at EFK. High clouds and the slight bump in wind should preclude fog at PBG and BTV. For MSS, 850mb flow will be off of Lake Ontario favoring some BKN035-060 overnight. Otherwise, light northerly winds will switch more southerly Wednesday.
Outlook...
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. Saturday Night: VFR. NO SIG WX. Sunday: VFR. NO SIG WX.
