Area Forecast Discussion National Weather Service Burlington VT 236 AM EDT Tue Apr 21 2026
WHAT HAS CHANGED
As of 235 AM EDT Tuesday...
No significant changes but the weekend is trending drier.
KEY MESSAGES
As of 235 AM EDT Tuesday...
1. Mostly dry and cool this week with a couple chances for light precipitation.
2. Trending drier for the weekend and early next week with near normal temperatures.
DISCUSSION
As of 235 AM EDT Tuesday...
KEY MESSAGE 1: An omega type block will set up over the middle part of the country for a large part of the week, keeping a relatively consistent stretch of weather. The main chance of precipitation occurs tonight as a weak shortwave dives southeast out of Canada.
Scattered showers are expected, with the highest probabilities of seeing precipitation over southern and western areas. Snow levels look to be between 1,000 and 2,000 ft during the precipitation so very light accumulations are possible in the higher elevations.
With liquid precipitation only expected to be in the range of a couple hundreths of an inch at most and with marginal temperatures, accumulations are expected to be under an inch. An even weaker round of precipitation is possible Wednesday night with a few sprinkles/flurries possible. The main feature to watch during this stretch are the fire weather elements. Today and Thursday will be the days with the lowest relative humidity. Relative humidity values look to be in the 20s and 30s today, with slightly higher values on Thursday. However, winds will be relatively light today, with gusts generally staying around and under 15 mph. Thursday will be windier, with northwesterly gusts between 20 and 30 mph possible.
KEY MESSAGE 2: Forecast trends are towards drier conditions for the upcoming weekend with medium/long range guidance indicating high pressure will remain over the region, shunting precipitation chances southward across southern New England and the Mid-Atlantic states.
Thereafter an omega-block pattern looks to set up early next week with an upper level ridge shifting over the forecast area for Monday and Tuesday. Near normal temperatures are expected with highs in the upper 50s to mid 60s, and lows mid 30s to mid 40s.
AVIATION /06Z TUESDAY THROUGH SATURDAY/
Through 06Z Wednesday...VFR conditions will generally prevail through the period. Current SKC will give way to increasing mid/high clouds advancing from west to east after 12Z, but will remain FEW-SCT through the day while lowering from 15,000 mid-morning to 8,000 by the end of the 24-hour period. Calm winds overnight will increase to 4-8kts after 14Z from the SSW except locally SE at KPBG.
Outlook...
Wednesday: Mainly MVFR, with areas VFR possible. NO SIG WX.
Wednesday Night: Mainly VFR, with local IFR possible. NO SIG WX.
Thursday: Mainly VFR, with areas MVFR possible. NO SIG WX.
Thursday Night: VFR. NO SIG WX.
Friday: VFR. NO SIG WX.
Friday Night: VFR. NO SIG WX.
Saturday: VFR. Slight chance SHRA.
