Area Forecast Discussion National Weather Service Burlington VT 1010 AM EDT Thu Sep 24 2020

SYNOPSIS. Dry weather is expected to continue through the weekend with just a chance of showers developing Sunday afternoon. Temperatures will continue the gradual warming trends with highs expected to warm into the mid 70s to lower 80s by Sunday. A frontal system is expected to bring some rain to the region on Monday with unsettled weather continuing through the first half of next week. Temperatures will return to seasonal normals following the cold front on Monday.

NEAR TERM /THROUGH FRIDAY/. As of 1010 AM EDT Thursday . Forecast is in good shape this morning. Only change made at this time is to sky cover, as area of mid-level clouds over southern Canada mostly has stayed to our north, leaving only wispy cirrus across northern New York and Vermont. More substantial cloud cover/partly cloudy skies, primarily close to the International border, will likely arrive this afternoon. Enjoy the sunshine!

Previous Discussion . A weak shortwave will track just north of the International Border this afternoon with a very slight chance for a shower or two across for northern Vermont. Otherwise, the period of drier weather is expected to continue to as surface high pressure builds in from the west. It won't be as sunny as it has been the past several days as westerly flow aloft helps to usher in moisture and cloud cover ahead of the advancing shortwave. Nevertheless, temperatures will once again be a few degrees warmer than the previous day with afternoon high temperatures peaking in the upper 60s to mid 70s. While we should see some cloud cover linger tonight, model soundings and MOS guidance is hitting fog hard once again across the northern Adirondacks and east of the Green Mountains with light winds and increasing moisture across the region. This fog will quickly lift between 8 and 9 AM on Friday with scattered clouds and highs in the lower to mid 70s across the region. Once again, the chances for any showers would be confined to far northern Vermont but any chances for rainfall are less than 15% with little to no accumulation with any showers that do pop up.

SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/. As of 343 AM EDT Thursday . The weekend's weather will be characterized by increasing southwesterly flow as our forecast area is sandwiched between Atlantic high pressure and low pressure to our northwest over Ontario. Will see southwesterly winds gradually increasing through the day Saturday (locally southerly up the Champlain Valley). Wind speeds by Saturday afternoon will generally be in the 5-15 mph range, with some gusty channeled flow up the Champlain Valley with gusts 15 to 25 mph locally near and along Lake Champlain. Ongoing warm air advection will result in highs in the mid to upper 70s Saturday. Will see a diffuse warm front pushing northward through New England during the day Saturday, so expect some increasing clouds through the day. Still looking predominantly dry on Saturday, although higher res guidance showing the potential for a few sprinkles over southern VT late in the day as the front moves in. Temperatures Saturday night will be very mild amid continued warm air advection . expect lows in the mid 50s to low 60s.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. As of 343 AM EDT Thursday . Winds will continue to increase during the day Sunday as pressure gradient further strengthens and a 40-50 kt low- level jet skims the northern part of the forecast area. Overall looking at surface winds 15 to 25 mph Sunday afternoon with some southwesterly (locally southerly in the Champlain Valley) gusts of 25 to 35 mph. Continuing to see a shift in the models towards drier conditions Sunday with the bulk of the rain associated with a series of Canadian low pressure systems now expected to stay north of the Canadian Border. Sunday will be another very warm day due to the magnitude of the warm air advection, with temps expected to top out in the upper 70s for much of the area.

The forecast for Monday onward still looks quite unsettled with a sprawling upper-level low developing over the central part of US/Canada. Monday will start off relatively warm with continued southerly/southwesterly flow as we are ahead of broad low. Temperatures will gradually cool towards the middle of next week as the low shifts eastward. Monday through Wednesday is still looking generally wet and showery, although still much difference in timing of waves of rain/fronts that will move through the area. Thus have kept PoPs in the 30 to 50 percent range for this timeframe.

AVIATION /14Z THURSDAY THROUGH MONDAY/. Through 12Z Thursday . A pocket of low to mid-level clouds has dissipated this morning with clearing skies developing across the region. This has allowed for locations in New York to approach their crossover temperatures with IFR fog ongoing at KSLK. The lingering fog will lift between 12Z and 13Z with light and variable winds and VFR skies prevailing through much of the remaining forecast period. Another round of IFR fog at KSLK and KMPV looks likely after 06Z once again.

Outlook .

Friday: VFR. NO SIG WX. Friday Night: VFR. NO SIG WX. Saturday: VFR. NO SIG WX. Saturday Night: Mainly VFR, with areas MVFR possible. Slight chance SHRA. Sunday: Mainly VFR, with areas MVFR possible. Windy with gusts to 30 kt. Slight chance SHRA. Sunday Night: Mainly VFR, with local MVFR possible. Chance SHRA. Monday: Mainly MVFR, with areas VFR possible. Chance SHRA.
