Area Forecast Discussion National Weather Service Burlington VT 923 AM EDT Thu Jul 29 2021
SYNOPSIS. Precipitation chances increase later this afternoon as a cold front approaches the region. Widespread rain showers are expected across the North Country through Friday morning. This front will usher in a much cooler airmass for Friday with high temperatures much below normal in the 60s to around 70. Saturday will bring a return to dry weather before the next wave of precipitation arrives on Sunday.
NEAR TERM /THROUGH FRIDAY/. As of 908 AM EDT Thursday . Rain continues to track eastward across New York with light rain currently working its way into the Saint Lawrence Valley. Slight updates were made to the forecast to account for the earlier onset of rain across this area and cloud cover was increased as well. Rain will continue its trek across the North Country, reaching the Champlain Valley by early afternoon. See previous discussion below:
Previous Discussion . Surface high pressure will continue to shift eastward throughout the day today as our next frontal boundary approaches from the west. Looking at current satellite and radar imagery, a complex of thunderstorms associated with an MCS across the western Great Lakes continues to propagate towards the east/southeast. This complex will remain to our south, however the area of showers with a few embedded thunderstorms just to the north of this feature, associated with the larger scale shortwave and surface low, will provide the focus for widespread rain showers later evening into tonight. Current thinking is that as this MCS moves across the mid- Atlantic the best moisture axis will remain tied to this feature and thus south of our area, in turn brining with it the best chances for any heavy rainfall. Rain should begin moving into the region after 18z, with widespread rain showers across the area by 00z. The probability for thunder still remains fairly low given nearly isothermal sounding profiles, however have mentioned a slight chance for our southern areas across northern New York and central Vermont as some weak elevated instability is present. Overall, this system will bring beneficial rainfall, especially to the northern portions of our CWA (which still remain in moderate drought). QPF amounts will be generally between 0.25-0.75", with the highest amounts across the Northeast Kingdom of Vermont.
Chances for rain showers remain throughout the morning hours on Friday as a secondary piece of shortwave energy and surface front cross the area. This boundary will usher in a much cooler and drier airmass as NW flow becomes established. While still July, this front will bring a small taste of fall with lingering clouds and highs in the low/mid 60s. Winds will be out of the NW 10-15 mph with gusts upwards of 20 mph.
SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY/. As of 507 AM EDT Thursday . Upper trough axis move east of the area Friday evening and northwest flow aloft develops over the region. This pattern will persist right through Saturday. Any showers over Vermont will quickly come to an end Friday evening as high pressure builds into the region. Dry weather is expected on Saturday, but temperatures will continue to be below normal. Highs will generally be in the mid 60s to lower 70s.
LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/. As of 507 AM EDT Thursday . Dry weather continues into Saturday night, but another upper level trough of low pressure will move into the region Sunday and Sunday night with showers becoming widespread across the area along with the potential for a few thunderstorms. Highs on Sunday will once again be below normal with readings in the upper 60s to lower 70s. High pressure returns on Monday and flow aloft will generally be from the southwest right through the middle of next week. As a result, the weather should generally be dry with a warming trend taking place. High temperatures by the middle of next week should be right around seasonal normals with highs in the mid 70s to lower 80s.
AVIATION /13Z THURSDAY THROUGH MONDAY/. Through 12Z Friday . Changeable aviation conditions expected through the TAF period. Lingering VLIFR fog/low clouds will persist at KSLK through 13z before lifting to VFR as high clouds move into the airspace. Elsewhere, VFR conditions will remain through the afternoon hours. After 18Z, chances for showers increase along with lowering ceilings to MVFR across all TAF sites. Showers will persist through the remainder of the TAF period with reductions in visibility down to 4 miles possible. Towards 06z, ceilings will lower to IFR as a secondary boundary crosses the area by Friday morning. Winds will be out of the south around 10 kt today, becoming light and variable overnight as precipitation overspreads the area. Towards 08z, winds will begin to turn out of the W/NW for northern NY terminals.
Friday: Mainly VFR, with local IFR possible. Chance SHRA. Friday Night: VFR. NO SIG WX. Saturday: VFR. NO SIG WX. Saturday Night: VFR. Chance SHRA. Sunday: Mainly VFR, with local MVFR possible. Likely SHRA, Slight chance TSRA. Sunday Night: MVFR/IFR conditions possible. Chance SHRA, Slight chance TSRA. Monday: Mainly VFR, with areas IFR possible. Slight chance SHRA.
