Area Forecast Discussion National Weather Service State College PA 339 AM EST Mon Feb 24 2020

SYNOPSIS. Another mild day with increasing clouds. Occasional light rain is expected to spread across the area tonight through Tuesday and could mix with snow at times over the northern tier. A change in weather pattern will take place by late week. Look for rain Wednesday afternoon to possibly end as snow Wednesday night. Gusty winds will direct much colder air into the region Thursday with snow showers across the Allegheny Plateau. Below average temperatures are expected to close out the month before trending warmer into the first week of March.

NEAR TERM /THROUGH TONIGHT/. Skies trended mostly clear after midnight. Similar to the previous two nights, expect some locally colder spots with calm winds to dip into the upper 10s/low 20s before sunrise.

Dewpoints should begin to tick upward today but minRHs are still forecast to drop into the 30-35 percent range to the southeast of I-99/80. Adjusted MaxT upward by a few degrees after outperforming the multi-model blend during the last 2 days.

Clouds will increase through the day but no precipitation is expected until after midnight. Followed hires guidance in spreading light precip sw-to-ne across the CWA through 12Z Tue. Temperatures remain marginally cold enough to support rain/snow mix across the northern tier with maybe a coating on non-paved surfaces at the highest elevations.

SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/. Not as warm on Tuesday (highs 5 to 10 degrees colder than Monday but still above late Feb. climo) with low clouds and occasional light rain. Spotty light rain along with pockets of drizzle and fog are expected Tuesday night as forecast soundings show moisture profiles becoming rather shallow and light sfc winds. Total rainfall forecast through Tuesday night is less than 0.25 inch.

A winter storm system continues to take shape for midweek with guidance showing deepening and slow moving/occluded sfc low pressure lifting northward across the region. Models have been indicating a more robust QPF signal for later Wednesday into Wednesday night in response to strong 500mb height falls, intensifying mid-upper trough and associated jet dynamics. A period of moderate rain appears likely Wed. PM. shifting from west to east. Wednesday night looks rather interesting with a possible rain-to-snow scenario setting up on the backside of the storm. This will be something to monitor going forward. Cold air is poised to arrive by the end of the period via gusty northwest winds. There is some potential (low confidence) for a period of heavy snow showers/squalls early Thursday morning across southwest and south central PA per SNSQ parameter. Also something to keep an eye on.

LONG TERM /THURSDAY THROUGH SUNDAY/. Much colder air will sweep across central PA by Thursday behind the departing low and associated cold front. This will set the stage for a much colder pattern through the weekend and frequent lake-effect snow showers over the northwest. Temps will end up around 5-15 degrees below normal late in the week and through the weekend.

AVIATION /07Z MONDAY THROUGH FRIDAY/. A clear sky and VFR conditions will continue through Monday AM. Clouds will increase through the day Monday but it is expected to stay dry until later Monday night. There could be a brief period of wet snow over the northwest at the onset of precip Monday night.

Outlook.

Tue-Thu . Periods of rain expected from midday Tuesday through Wednesday before rain mixed with then changes to some snow or snow showers Wednesday night into Thursday Fri. A chance of snow showers across the north and west. Dry otherwise with VFR conditions.

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.

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