Recreational Forecast

Mountain Forecast:

The recent wave of heat has made outdoor recreation a bit unpleasant if you have found yourself away from a water source. Expect another hot and increasingly muggy day today as we await a cold front to cross the region. Most mid-elevations are able to break back into the 80s today but with less sunshine than the last few days. Although less sunny dewpoints will be on the rise making for increasing humidity levels. Showers and storms will continue to bubble up this afternoon as the cold front drops south. Some heavy downpours are a sure bet with some damaging winds. If you are finding reprieve from the heat and humidity around a water source today make sure to be prepared for rapidly changing conditions. A brief break from heat comes to round out the work week as high pressure passes nearby. Although temperatures trend back above normal for the weekend before a much cooler air mass finally arrives next week. 

Wind At Lower Elevations:
Overall winds counite to be light today. Although thunderstorms this afternoon make for gusty to possibly damaging wind. This will make for dangerous conditions on the open waters. Make sure to be aware of rapidly changing conditions later today.

Detailed Discussion

The upper level ridge which made for desert-like dewpoint depressions yesterday finally breaks down today. This will allow a meager cold front to shift through the region from the northwest this afternoon into the overnight hours. The front provides the first measurable rainfall of the month for many, as showers and storms gradually take over the region throughout the day. The front does not provide relief from the heat just yet as highs over the valleys rise back to around 90, with a moisture rich airmass surging back overhead. Therefore expect heat indices in the 90s today as dewpoints approach the 70 degree mark. Expect showers and storms over Northern New York this morning to shift into Vermont throughout the rest of the day. Although no severe storms are expected some stronger storms are a possibility. Areas north of Rutland have the best chance to see some stronger storms, which will provide heavy downpours and gusty winds, with a chance of some damaging winds as well. The front likely swings through piece-meal so a few showers linger tonight into tomorrow morning. Any lingering showers tomorrow morning likely come over areas south of Rutland. It will take some time for a drier and cooler airmass to filter in overhead therefore it will be stuffy tonight, yet again, with lows in the 60s.

Transient high pressure then builds overhead from the northwest tomorrow into Friday. This gives a quick break from uncomfortable conditions. Expect widespread highs in the 80s tomorrow with gradually increasing sunshine. Real relief from the heat finally comes tomorrow as the region sees lows in the much more comfortable 50s, with even some upper 40s being found over the cooler northern hollows. Friday will be the pick of the forecast as it will be dry and very sunny with tolerable temperatures. Highs to round out the work week will be a good 10 degrees cooler than what we saw earlier this week as they rise into the upper 70s to mid 80s, a dry continental air mass will help keep the humidity low. 

High pressure will quickly move to our southeast this weekend leaving the door open for another warm up as southerly return flow filters overhead behind this surface feature. Therefore expect some highs in the lower 90s to return to the border valleys with warm overnight lows. Our stretch of heat will not be as prolonged as a cold front returns Sunday into the start of the new week. This will help temperatures moderate back to around and then below normal for the start to middle of next week, allowing for more typical Northern New England late summer weather

Farm & Garden

Rainfall Forecast:

A meager cold front supplies generally less than a half inch of rain throughout the region. Although heavy downpours could provide some locally higher totals up to a full inch. 

Drying Conditions:

Fair to poor drying conditions come today as dewpoints will be on the rise ahead of a cold front. Showers and thunderstorms all impede on drying conditions. Good to excellent drying conditions develop through the day tomorrow and linger into Friday.

Frost:

No chance of frost until at least the end of this month.
