We are in for a gloomy wet evening across Central PA. Fog may be thick at times. Already seeing visibility down to near a mile or less, combine with mist and drizzle, use caution traveling. Temperatures are mild in the 40s and will hold steady.
Traveling along the east coast may be slow and tricky. Call ahead for flight info to make sure your flight is on time or if delayed. Also, if you are hitting the roads, be prepared for a slow ride, as rain is expected all along the coast from Main to Florida.
Several disturbances will traverse the area starting in the morning, then followed by another mid-day and yet another in the evening and overnight period. Rain is likely in the morning then we get a break before another batch of rain moves in mid-day. A more significant disturbance along with a cold front encroaches on the area during the evening and overnight bringing yet more rain. It will be a wet but very warm day as strong warm air advection boost temperatures to the upper 50s. Some models even have temperatures as warm as the mid 60s. The record tomorrow is 62 set in 1990. We’ll be watching closely! Don’t think we’ll get that warm but the idea is there that it will be a surge of milder air, indicating how strong this system is. Rain ends overnight then the winds accelerate quickly pulling in cooler, drier air for Christmas Day.
Some areas could pick up an inch of rain.
Cooler air wraps around the system, sharply changing our temperatures for the holiday. Actual highs will be just after midnight. Temperatures will fall through the day with afternoon temperatures mid 40s but feel chillier with the strong winds. A few flurries in the higher elevations may be possible too. Clouds will mix with the sunshine for much of the day but we look to stay dry for the holiday.
High pressure builds in for Friday and Saturday. Shot of cooler air and windy conditions will be short lived. Sunshine returns and temperatures will be well above average in the upper 40s to near 50. We’ll be watching our next system for Sunday and Monday. Models show different scenarios for each day. It does appear it will be cooler and we could see rain or snow showers depending on track of our next wave of low pressure. More fine tuning to the forecast to come in the next few days as we track the evolution of each model run.
