AREA FORECAST DISCUSSION National Weather Service Albany NY 952 AM EDT Mon Apr 15 2024

SYNOPSIS
An upper level disturbance will produce some isolated to widely scattered showers for areas mainly north of Interstate 90 today, otherwise it will be partly sunny with seasonable temperatures. High pressure will bring dry and mild weather for Tuesday and Wednesday, with unsettled weather returning later in the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/
UPDATE
As of 950 AM EDT
We let the Dense Fog Advisory expire with localized dense fog continuing near the Hudson River Valley from Hudson, Albany north to Glens Falls. We issued and SPS to replace the NPW and it runs until 11 am. Some localized areas of dense fog may linger until then.

The 12Z KALY sounding shows a strong low-level radiative inversion below 925 hPa with the fog/stratus below it. Stronger winds from aloft and some sunshine should continue to break up the fog. An upper level disturbance will produce some isolated to scattered showers mainly across the southern Dacks, Lake George Region into VT late this morning into the afternoon. It will become breezy with west/northwest winds 10-20 mph with some gusts about 30 mph or with mixed clouds and sunshine. Temps will be seasonable for mid-April.

PREV DISCUSSION [358 AM EDT]...
After any fog lifts, expect partly sunny skies later this morning through afternoon. Cold air aloft may promote isolated to scattered rain showers/sprinkles for areas north of I-90 later this morning into the afternoon.

It will become breezy later this afternoon as mixing depth increases, with some gusts possibly reaching 25-30 mph, especially within the Mohawk Valley/Capital Region and Berkshires, as well as across portions of the SE Catskills, mid Hudson Valley and NW CT.

Afternoon high temps should reach the upper 50s to lower 60s within most valley areas, except upper 60s to lower 70s across the mid Hudson Valley. Higher terrain areas across the southern Adirondacks and southern VT may only reach the upper 40s to lower 50s.

SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/
Isolated showers/sprinkles may persist across portions of the southern Adirondacks/southern VT through this evening, otherwise dry weather is expected through at least Wednesday morning. It will become breezy once mixing depth increases Tuesday afternoon once again, with west/northwest winds possibly reaching 25-30 mph across portions of the Mohawk Valley/Capital Region and Berkshires. Lows tonight and Monday night in the mid/upper 20s to lower 30s across the southern Adirondacks and upper Hudson Valley, with mid 30s to lower 40s elsewhere. Highs Tuesday afternoon in the lower/mid 60s for valley areas, and 55-60 for most higher terrain areas.

For Wednesday, latest guidance continues to suggest a slower arrival of clouds and showers with next system, as upper level confluent flow keeps high pressure closer to the region. For now, have a slow increase in clouds, with low chances for showers across western areas late in the day, while remaining dry from the Capital Region and points north and east. However, there remains some uncertainty in the timing of any incoming showers. Assuming showers hold off, max temps should reach the upper 50s to lower/mid 60s in valley areas, warmest for the upper Hudson Valley region.

Showers slowly advance north and east Wednesday night, however dry air from lingering high pressure may tend to erode showers from reaching portions of the SE Adirondacks, upper Hudson Valley and southern VT. Lows mainly in the mid 30s to lower 40s.

LONG TERM /THURSDAY THROUGH SUNDAY/
Long term period begins at 12z Thursday with upper troughing to our west, and an associated surface low tracking north of the Great Lakes. Upper ridging may help to keep us relatively dry through the first part of the morning, although chances for showers increase in the afternoon as the system's occluded front tracks across the region. The front will be slow-moving, so some showers could linger into Thursday night. With more clouds and showers around, it will be a few to several degrees cooler than Wednesday with highs mainly in the 40s (terrain) to 50s (valleys) and lows in the 30s to 40s.

Friday into Saturday...Upper troughing slides eastwards, helping to drive a stronger cold front through the region. There are some significant timing differences with the frontal passage in numerical guidance, so at this time will just lean towards the middle ground NBM solution with the frontal passage daytime Saturday. Regardless of the exact timing, additional showers are expected with the cold frontal passage. Behind the cold front, cooler and drier weather is expected for the second half of the weekend into early next week with cold/dry advection and high pressure building in from the west.
Temperatures will likely run below normal for this timeframe. The CPC is expecting near to sightly below normal temperatures and near to slightly below normal precipitation for days 8 to 14.

AVIATION /14Z MONDAY THROUGH FRIDAY/
Through 12z Tuesday...Mainly IFR or lower conditions with widespread fog and low stratus as of 6:30 AM EDT, although low clouds/fog have at least briefly scattered out at PSF. Overall trend should be for improving conditions this morning, and current thinking is that all terminals should see VFR conditions from around 14z onwards.
However, fog and low stratus resulting in IFR conditions could stick around through around 13z, and have indicated this with tempo groups at all TAF sites.

Once conditions improve back to VFR this morning, they should remain VFR through the end of the TAF period. Will see SCT to BKN cigs through the afternoon with cloud bases around 4000 ft, but clouds should diminish after sunset with the loss of daytime heating. Just a few passing mid-level clouds expected overnight through 12z Tuesday.

Winds are light and variable this morning, but increase to around 10 kt from the west by late morning, with some gust to around 20 kt expected this afternoon. Winds diminish to around 5 kt or less after sunset, remaining at 5 kt or less mainly from the west through 12z Tuesday.

Outlook...

Tuesday Night: No Operational Impact. NO SIG WX.
Wednesday: Low Operational Impact. Slight Chance of SHRA.
Wednesday Night: Moderate Operational Impact. Chance of SHRA.
Thursday: Moderate Operational Impact. Chance of SHRA.
Thursday Night: Moderate Operational Impact. Chance of SHRA.
Friday: Low Operational Impact. Slight Chance of SHRA.
