Surface high pressure over the region this morning will provide dry and seasonal weather to the North Country through tonight. Warm and more humid conditions return Tuesday with chances for showers and thunderstorms Tuesday afternoon through the remainder of the work week, especially Wednesday and Wednesday night, as high pressure off the Atlantic coast maintains a warm moist southwest flow into our area. && .NEAR TERM /THROUGH TUESDAY/... As of 319 AM EDT Monday...A welcomed break from active and humid weather is the forecast for today as surface high pressure centered just south of the area will provide fair and dry conditions through tonight. After early morning burns off high clouds will increase from southwest to northeast and some fair weather cumulus will develop this afternoon, but no precipitation is expected. 925mb temps rise slightly from yesterday to around +20C supporting highs mainly in the upper 70s to low 80s, with comfortable humidity as dewpoints will fall into the low/mid 50s this afternoon. Clouds continue to increase going into tonight associated with the return of moist southwest flow between an approaching upper trough and the Bermuda high parked off the Atlantic coast. Thinking clouds will inhibit any fog development despite light boundary layer flow with lows a few degrees milder than the previous night in the 50s to low 60s. For Tuesday, have backed off PoPs quite a bit from the previous forecast based on model trends. Mid-level heights are still rising across most of the area through the day, and latest trends are for the arrival of higher PWATs to be delayed until Tuesday night or Wednesday. In addition, little instability is present along with limited forcing, all pointing to less chances for precipitation. That said, across northwest New York closer to the approaching upper trough I could see a few showers developing so will maintain some low chance PoPs there, but from the Champlain Valley eastward think it will be a dry day. 925mb temps don't change much from the previous day so highs will once again be in the upper 70s to low 80s, but humidity will begin to increase as dewpoints climb into the low/mid 60s. && .SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY/... As of 307 AM EDT Monday...Mainly a persistence forecast through Tuesday night and Wednesday with one notable adjustment, namely to lower pops downward quite a bit Tuesday night. Latest model trends suggest that despite increasingly moist southerly return flow, the overall lack of dynamic forcing should allow any scattered afternoon convection on Tuesday to generally wane overnight with loss of insolation. As such I've carried only token 20/30 pops overnight, focused mainly across the south and west in closer proximity to deeper moisture plume. Low temperatures to range through the 60s to locally near 70 at KBTV. By Wednesday that plume rides northeast into our region. This, along with noticeable, albeit weak diffluence aloft in advance of a dampening shortwave trough to our west should be sufficient to drive scattered to numerous showers and storms across the region. PWATS in the 1.7 to 2.0 inch range should ensure locally heavy downpours in more robust cells. At least some modestly robust instability and deep layer shear will also be present so a few cells may also trend on the stronger side. Time will tell. It will definitely feel more summery as dewpoints climb well into the 60s to around 70 and daytime highs top out in the upper 70s to mid 80s. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... As of 307 AM EDT Monday...The main theme for late week into next weekend is for a continuation of warmth and humidity across the region as deep layer western Atlantic ridging holds semi- permanent offshore. This will keep a steady flow of moist south to southwesterly flow across our region with near daily chances of showers and a few storms, not uncommon for early August. This is not to say that it will be a washout on any of these days, just to say the threat is certainly non-zero with highest coverage in the afternoon to early evening during and just after peak heating. Given the expected scattered nature of the activity afternoon PoPs will generally range from 30-40% on Thursday/Friday, then slightly lower (20-30%) by next weekend as deeper heat and some evidence of building subsidence aloft drift into the area. As discussed above, it will certainly feel quite warm and humid with daily highs in the 79-86 range Thu/Fri, then well into the 80s to locally near 90 in warmest spots by the weekend. Lows to range mainly through the 60s to lower 70s. With these trends, it seems a safe bet to assume the A/Cs will be running steadily through much of the Thu-Sun time frame. && .AVIATION /07Z MONDAY THROUGH FRIDAY/... Through 06Z Tuesday...VFR conditions will largely persist through the next 24 hours with locally dense fog developing across eastern Vermont valleys tonight. Only terminal to be affected by fog will be KMPV where LIFR is expected from 08-12Z. After 12Z, we'll see more fair weather cumulus clouds develop through the day and continue into tomorrow night. Light and variable winds overnight will trend south/southwesterly <10 kts during the afternoon and back to nearly calm after 00Z Tuesday. Outlook... Tuesday: VFR. Chance SHRA, Chance TSRA. Tuesday Night: Mainly VFR, with local MVFR possible. Likely SHRA, Chance TSRA. Wednesday: Mainly MVFR, with areas VFR possible. Likely SHRA, Chance TSRA. Wednesday Night: VFR.
