Philly Winter Weather Update- Mon 11 PM
Tonight's GFS model has much less snow than the NAM. It cranks out only 0.30 inches water. If we average the NAM and GFS, we're closer to 5 inches snow by daybreak. I guess we'll see tomorrow!

Philly Winter Weather Update- Mon 10 PM
Tonight's NAM model shows significantly more snow for Philadelphia. The NAM cranks out almost .50 inches water, falling as snow. The NAM has done well this season, so I'm raising the predicted snowfall for Philadelphia to 6-7 inches snow tonight. The storm still ends by daybreak tomorrow.

Philly Winter Weather Update- Mon 7 PM
The NAM and GFS models continue to crank out about .25 to .35 inches water falling as snow and ending before 7 AM Tuesday. This is for gridpoint PHL airport. Areas just to the north (NE Philadelphia airport) have about .10 inches less, so we will be on the northern fringe.
The latest HRRR model shows 3, possibly 4 inches for Philadelphia with areas just south of Philadelphia, southern Chester county, getting 5 inches.
I'll update later if things change.

Philly Winter Weather Update- Sun 6 PM
Well, the models have moved back to having some light snow for us later Monday night. Both the GFS and NAM crank out about 0.2 inches of water with upper air temperatures supporting snow.
Light snow is predicted to fall starting early Monday evening and should be over by Tuesday morning. Total snow amounts about 2-3 inches Tuesday morning. Stay tuned.

Philly Winter Weather Update- Sat 11 PM
I know the radio stations are still talking about snow for Monday night into Tuesday, but the GFS and the NAM models are suppressing the snow to our south. It appears the low will slide to our south and we will stay dry.

Philadelphia Weekend Weather Forecast- Fri AM
Yet another [weaker] low pressure system will affect our weather this weekend!
A coastal low will move just east of us on Saturday. The thermal profiles of the NAM FOUS data have changed a bit and are somewhat warmer. It's again showing upper air temps too warm for snow. The precip may start as light snow before daybreak Saturday, but will quickly change to sleet and then rain. Areas north and west of the city may have freezing rain on sidewalks and other surfaces. Road surfaces will be mostly wet. The precip changes back to light snow Saturday evening. Little or accumulation is now expected.
More storms on the way for next week, both Tuesday and a potential significant storm next Thurs. Stay tuned!
Sat 2/5: Rain and some freezing rain from the city far north and west. High 34. Changes back to light snow in the evening. Little or no accumulation expected.
Sun 2/6: Mostly sunny and cold. High 39 (Normal high is 41)

Philadelphia Weekend Weather Forecast- Thur PM
Yet another [weaker] low pressure system will affect our weather this weekend!
A coastal low will move just east of us on Saturday. The thermal profiles of the NAM FOUS data did well with the precipitation type this past Tuesday. It's again showing upper air temps too warm for snow, but temps in the lower atmosphere supporting sleet and freezing rain. The precip may start as snow before daybreak Saturday, but will quickly change to sleet and freezing rain. According to the NAM, temps will struggle to get above freezing, causing some ice and freezing rain during the day. Road surfaces will be mostly wet. The precip changes back to snow before ending, giving us an inch or two by Sunday morning.
More storms on the way for next week, both Tuesday and a potential significant storm next Thurs. Stay tuned!
Sat 2/5: Sleet and freezing rain from the city north and west. High 34. Changes back to snow in the evening, 1-2 inches snow possible by Sunday morning.
Sun 2/6: Mostly sunny breezy and cold. High 38.
