.DISCUSSION... Key Messages:
- Dry conditions areawide through the remainder of this week with near to above normal temperatures.
- Rain chances increase Saturday night through Monday, with a low chance of a thunderstorm Sunday afternoon.
As of 17z, a ridge of surface high pressure remains well entrenched across much of the Northeast into the Southeast. Low pressure was located off the coast of the Outer Banks, with some clouds seen this morning and early afternoon from it mainly in the Mid Hudson Valley and northwest Connecticut. Temperatures as of this writing were in the upper 60s to low 70s.
Tonight through Saturday...
Our dry and tranquil weather pattern will remain in place through the end of this week as surface high pressure and ridging aloft remain in place. Despite that, there is one feature to note. A weak cold front currently in place just north of the Great Lakes will continue to dive southeast tonight into Thursday, and will reach the region Thursday night/early Friday. With weak lift and a moisture starved airmass ahead and along the front, no precipitation is expected. However, winds will be noticeably higher across the Hudson Valley with channeled flow and in downslope areas of the ADKs, with gusts up to 20 mph possible Thursday afternoon and evening.
Temperatures will be near to above normal with highs in the mid to upper 70s outside of high terrain (values here in the 60s), with overnight lows in upper 40s to low 50s outside of high terrain (values here in the low 40s).
Saturday night through Monday...
Our next chance of measurable rain arrives from the northwest Saturday night into Monday, as another weak surface cold front and trailing cold core low pressure move into the region. While there remains some uncertainty in the speed and exact location of the system, confidence continues to increase of a measurable rain for much of the region. NBM probabilities continue to advertise around a 50% chance of at least 0.01" of rain for the area, though some localized higher probabilities of around 60-80% are being noted in the latest guidance mainly in the higher terrain of the ADKs. Deterministic guidance also remains in good agreement of a measurable rain, though amounts are widely variable depending on guidance due to differences in forcing, available moisture and potential downsloping effects. In addition, low to medium levels of instability due to steep mid level lapse rates will promote development of isolated to scattered thunderstorms, especially Sunday afternoon. Continue to monitor the latest forecasts for more updates.
Temperatures are favored to be near to below normal, with highs in the upper 60s to mid 70s outside of high terrain (values here in the low 60s), and lows in the upper 40s to low 50s outside of high terrain (values here in the low to mid 40s)
Monday night on...
Dry conditions will return to the area early next week with high pressure. Near normal temperatures are favored.

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/... Visible satellite imagery shows clear skies over the region for KGFL, KGFL and KPSF. Meanwhile, KPOU is on the fringe of the clouds from a coastal wave, with some sct cumulus and passing high clouds there. For all sites, it will stay VFR through this evening with light winds under 5 kts.
For tonight, skies will stay clear and winds will be calm. With the good radiational cooling, some fog will develop at KGFL. It may begin as early as 02z, but should be in place by 04z-05z at the latest, with IFR/LIFR visibility there through the late night hours. Elsewhere, fog looks likely less due to a higher t/td spread, although cannot totally rule out a brief period of fog at KPSF right around sunrise. Have included some MVFR mist there for now and will continue to assess fog potential for all sites based on late day trends. Any fog or mist should dissipate by 12z, allowing for VFR conditions to return.
On Thursday, flying conditions will stay VFR through the entire day with fairly clear skies once again. Surface winds will be light from a northerly direction around 5 kts.
