8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 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 1015 PM EST Sat Jan 23 2021
SYNOPSIS. High pressure will build across Pennsylvania during the second half of the weekend. Low pressure lifting out of the Mississippi Valley will spread a wintry mix across the state Monday night into Tuesday. Another southern stream shortwave could potentially affect the area Thursday, then high pressure should build in at the end of next week.
NEAR TERM /THROUGH SUNDAY NIGHT/. Radar still showing a few narrow bands of light lake effect snow across the northwest mountains at 03Z. Hi-res models suggest any additional accumulations should be limited to a fresh dusting over parts of Warren, Mckean and Potter counties overnight.
Otherwise, expect fair weather tonight with a shrinking area of stratocu across the northwest half of the forecast area, as high pressure builds in. Breaking clouds and a diminishing wind should allow temperatures to fall into the teens over most of the area late tonight and around 20F over the Lower Susq Valley.
Warm advection preceding a weak shortwave approaching from the midwest will spread lowering and thickening cloud cover across central Pa Sunday, with a bit of light snow possible late in the day across the western counties. Guidance brings temperatures back up on Sunday. After a cold start, readings should approach climatological averages by mid afternoon.
The most significant forcing at nose of low level jet sweeps across southwest Pa during Sunday evening. Hi-res models indicate a dusting to an inch of snow is possible during this time over the Laurel Highlands, where there will be a bit of orographic enhancement. Elsewhere, any precipitation will likely be limited to no more than a few flurries.
SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. There is increasing confidence for a widespread and quite impactful winter weather event late Monday into Tuesday with the possibility of snow, sleet, and freezing rain. Model guidance has kept the farther north track of the system today compared to the last few days.
The event seems to begin as a period of snow or wintry mix in Southwest PA and spread north Monday night, ending as light snow or light rain late Tuesday or Tuesday night. How far north sleet mixes into snow is still unclear at this time, but for now it seems the Northern half of PA will see more snow and the Southern half might see more of a wintry mix. The greatest chance of heavy snowfall will generally be from I80 on north with wintry mix to the south. The highest threat for significant freezing rain will be over the Laurels, especially in Somerset County. The main impacts from this event will be the potential for difficult travel from Monday evening through Tuesday afternoon.
The most uncertainty lies in the precip amounts and types with this storm. As far as amounts, models today look more like the EURO did yesterday with less overall precip and a more strung out system with the coastal low taking over quicker and much of the moisture being drawn offshore. I trended more toward WPC guidance vs the beefier NBM with this update. The wedge of cold air looks a little stronger over the eastern half of the forecast area which would promote less sleet and a longer period of snow, but with less precip overall this still doesn't look like a major snow maker.
A bit of light mixed precipitation could linger into Tuesday night associated with departing southern stream shortwave.
LONG TERM /WEDNESDAY THROUGH SATURDAY/. All medium range guidance supports fair and milder weather Wednesday, as upper level ridging builds into the state. Another southern stream shortwave lifting out of the Mississippi Valley could affect the area Thursday. All guidance currently shows rapid cyclogenesis off of Cape Hatteras Thursday, as southern and northern branches of the jet phase off of the east coast. Southern Pa could be on the northern periphery of the precipitation shield, thus will continue to carry chance POPs of snow, focused primarily over the southern tier. Latest GEFS and ECENS both support fair and seasonable conditions returning at the end of next week, as surface high builds in from the Grt Lks.
AVIATION /03Z SUNDAY THROUGH THURSDAY/. At 03z, northwesterly flow across the Great Lakes continues to produce MVFR cigs (1-2 kft) and spotty flurries across the western highlands. Cigs have even dropped to just below 3 kft over the central mountains (AOO and UNV). Farther to the east, cigs in the Susq Valley are generally VFR (4-5 kft).
It is beginning to look like the low clouds may be slow to budge overnight, but conds should become VFR area-wide during the day on Sunday. High and mid-level clouds will already be on the increase, however, and a bit of light snow is even possible towards evening across the west.
Outlook .
Sun . Generally VFR conds.
Mon . Restrictions developing as snow begins to overspread the area from SW to NE.
Mon night - Tue . Widespread restriction with light snow north and a wintry mix south.
Wed . Becoming VFR.
Wed night - Thu . Restrictions possible with a chance of snow.
CTP WATCHES/WARNINGS/ADVISORIES. None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
