.SYNOPSIS... Persistent dry conditions characterized by pleasant afternoon temperatures and morning fog for river valleys continues with high pressure in place through mid week. A dry cold front will move through Thursday bringing northerly breezes and possibly enhancing fire weather concerns given dry vegetation associated with ongoing drought. The next chances of widespread rain will hold off until the weekend into the beginning of next week.
&&
.NEAR TERM /THROUGH THURSDAY NIGHT/... As of 200 PM EDT Wednesday...High pressure will remain over the region through the near term, aside from a weak surface cold front which will drop across the area on Thursday. Another good radiational cooling night will lead to some valley fog once again. Minimum temperatures tonight will range from the mid 50s close to Lake Champlain down to around 40 in the colder spots of the Dacks and Northeast Kingdom of Vermont. On Thursday the aforementioned weak surface cold front drops across the area and will mainly only notice an increase in clouds and gusty winds out of the north. Gusty winds could lead to some fire weather concerns, but dewpoints will be higher due to cold frontal passage. Regardless, fuels are dry so gusty winds could encourage fire spread if there were any fires. Maximum temperatures on Thursday will range from the mid 50s to mid 70s. Surface high pressure will build back into the area Thursday night, and lows will drop off with valley fog formation once again, minimum temperatures will range from the upper 40s to mid 30s.
&&
.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... As of 200 PM EDT Wednesday...Friday and Friday night will be cool and dry, no significant weather is expected. Sunny skies again on Friday but maximum temperatures will reach the mid 60s to lower 70s. Some clouds will move into the area Friday night associated with shortwave energy passing overhead, which will prevent temperatures from dropping off too much. It may also lower chances for fog formation.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/... As of 146 PM EDT Wednesday...Confidence in seeing a period of showers over the weekend and into early next week is increasing. An upper trough will swing through eastern Canada while a series of shortwaves rotate down through the base. Exact timing/placement/strength of these is still uncertain due to differences in models, but at this time at least one of these looks to cross our area over the weekend, bringing showers and potentially even a few rumbles of thunder. At this time the most likely time for showers/isolated storms is Sunday, but some guidance shows a preceding shortwave moving overhead Saturday, so can`t totally say for certain that either day will be dry. It`s still difficult to discern amounts, but do note that probabilities for 24- hr rainfall over 0.50 inch are still fairly low (less than 30%), so at this point don`t anticipate heavy rainfall. But we`ll continue to monitor trends as the weekend draws closer.
Otherwise, the precipitation chances should decrease heading into the work week as the trough shifts eastward while ridging builds eastward from the Midwest. Daytime temperatures will be a little cooler over the weekend, particularly if the weather does trend more showery, with highs still fairly pleasant in the mid 60s to low 70s. We will then trend warmer by mid week as highs should be in the 70s areawide. Overnight lows will be fairly seasonable in the mid 40s to mid 50s.

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/... Through 18z Thursday...Another TAF period with prevailing VFR outside of any valley fog. KMPV/KSLK will see LIFR/VLIFR in dense fog 09z-12z Thu, otherwise expect FEW-SCT clouds AOA 5000 ft through the period. Winds variable around 5 kt through 00z Thu, then near calm and terrain-driven overnight. Frontal passage will bring slightly increased cloud cover and N/NW winds 8-15 kt with gusts to 20 kt after 14z.
Outlook...
Thursday Night: VFR. Patchy BR. Friday: VFR. NO SIG WX. Friday Night: VFR. NO SIG WX. Saturday: VFR. NO SIG WX. Saturday Night: VFR. Chance SHRA. Sunday: Mainly VFR, with local MVFR possible. Chance SHRA. Sunday Night: VFR. Slight chance SHRA. Monday: VFR. Slight chance SHRA.
