Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Area Forecast Discussion National Weather Service State College PA 1251 AM EST Tue Feb 18 2020
SYNOPSIS. A period of accumulating snow north, and rain south very late tonight and Tuesday morning will precede an area of low pressure moving northeast across the Great Lakes. The snow will accumulate 1 to 3 inches across the mountains of north central before changing to rain during the mid to late morning hours Tuesday. A coating to one inch of snow is possibly on colder, grassy surfaces near the Interstate 80 corridor.
Rain will exit the rest of the area later in the afternoon Tuesday, followed by a mainly dry weather pattern for the end of the week. Temperatures will trend colder with another brief shot of arctic air for late week.
After a mild start, temperatures will trend colder with another brief shot of arctic air for late week.
NEAR TERM /UNTIL 6 AM THIS MORNING/. Thickening clouds will overspread the region overnight in advance of low pressure lifting north through the Grt Lks. Regional radar loop at 03Z shows a good deal of virga across eastern Ohio and western Pa. However, fgen forcing is supporting a narrow band of higher returns over northwest Pa, which could make it into northern Pa late this evening in the form of a brief burst of light snow.
The bulk of the precipitation will arrive after 06Z, when warm advection associated with a potent low level jet lifts across the northwest part of Pa. Have therefore kept idea of the highest POPs of around 100 pct across the northwest counties and the lowest POPs of around 20 pct across the southeast corner of the forecast area.
Latest model soundings and earlier ensemble data continue to indicate there will be enough cold air for wet snow across the northern mountains and even a brief initial period of snow possible further south before a change to rain. 12Z HREFV2 indicates the snow could briefly fall heavily over the north central mountains around dawn, as the strongest forcing at the nose of the low level jet lifts through.
Temps should dip early tonight but then level off as the clouds lower and thicken, a SSE wind kicks up, and warm advection precip spreads into the area after midnight. Lows will range from around 30F across the northern tier to mid 30s in the south.
SHORT TERM /6 AM THIS MORNING THROUGH 6 PM WEDNESDAY/. A slushy, sub-advisory snowfall over the northern mountains should change to rain by around 15Z Tuesday, based on the latest model depiction of warmer air surging north ahead of Grt Lks low. Marginal surface temperatures of around 32F Tuesday morning will likely result in snow totals being partly dependent on elevation. However, most spots across the northern counties should fall within the 1-3 inch range.
The trailing cold front is progged to push southeast across central Pa during the afternoon and early evening, accompanied by lingering light rain. The front end threat of lingering rain showers should exit the southeast counties Tuesday evening. High pressure ridge building in behind the front should bring clearing skies across most of the region later Tuesday night. However, upslope flow could potentially yield stubborn low clouds across the Allegheny Plateau.
LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. An upper trough and pool of seasonably cold air is progged to swing through the northeast CONUS Wednesday into Thursday. Surface ridging and associated low inversion heights indicate any lake effect activity will be quite light, with only light snow showers/flurries possible across the Allegheny Plateau.
By late week, the center of a large surface high is progged to overspread the region, ending the threat of lingering lake effect flurries and likely accompanied by abundant sunshine Friday-Saturday. Below normal temperatures should give way to milder conditions by next weekend, as the high passes off the coast and a return southwest flow develops. Both the ECENS and NAEFS indicate a weakening southern stream shortwave will approach by early next week, bringing our next chance of precipitation, likely in the form of rain.
AVIATION /06Z TUESDAY THROUGH SATURDAY/. 06Z TAFS sent.
Main change was to add a line just after sunset, for the wind shift with the front and improving conditions.
First band on the radar from southwest NY to northeast PA. Not much being reported, some light snow at ELZ in southwest NY.
Earlier discussion below.
VFR expected to prevail through midnight with only high clouds moving through the region. After midnight, precipitation will overspread across northern/central airfields. Rain to snow at BFD with rain/snow mix at UNV and IPT. Heavy snow at times possible Tuesday morning, especially at BFD and IPT.
During the day Tuesday, snow will transition to all rain and drop vis/cigs areawide. LNS and MDT may be spared if batch of showers falls apart by the time it gets to SE PA.
Tue night . Mainly MVFR to IFR Ceilings across the Northern and Western Mtns with VFR to MVFR cloud bases elsewhere into Wed morning.
Wed PM-Sat . Mainly VFR conditions anticipated as a large area of Canadian high pressure moves southeast to the Central Appalachians by Sat morning.
CTP WATCHES/WARNINGS/ADVISORIES. None.
