[su_note note_color=”#ffffff”]Updated Sun 07:03 AM — Late night models have backed off of the cloudiness in PHL, but keep the morning cloudiness prediction from Norristown, west and north. [/su_note]

[su_note note_color=”#ffffff”]Updated Sat 11:13 PM — Tonight’s models have considerable mid-level cloudiness Sunday morning, more sun in the afternoon .[/su_note]

Last night’s forecast went pretty good.  I checked our home’s security cameras and we had some snow flurries about 5:10 AM this morning. The temperature early this morning was 31º.

We also had the clouds move in this afternoon and the radar currently shows some widely scattered sprinkles.

Tonight’s minimum temp  35.4º sd 1.6º

The forecast for Sunday hasn’t changed much .  We’ll still be under the influence of an upper air trough so temperatures, while warmer than today, will still be below average.

• Some cloudiness in the morning especially north and west of the city, then mostly sunny.
• Winds WSW 10-12 mph with gusts to ~ 20mph
• High temp 61.3º sd 1.3º

Cold high pressure will build in behind a strong cold front, expected to move through about 10 PM Friday night with an increase in winds from the NW and wind gusts to 35 mph.  Temperatures will drop close to and below 32º by morning in many areas.

As mentioned this morning, there have been some changes in the model forecasts for Saturday:

• QPF is lower than previously expected, about 0.5 inches of rain total by midnight.
• Cold air scours out most of the moisture more quickly.  Decreased chance of snow flurries tonight.
• Temperatures look to be colder than previously forecast, below 32º in many areas by daybreak.
• Less moisture post-frontal passage means sunshine early Saturday morning.
• Instability clouds move in after 12 noon, with sprinkles and possible snow flurries. Some sunny breaks also possible.
• High temp 48.3º sd 2.0º

There are differences in the models with the amount of clouds and possible showers/flurries on Saturday afternoon, but expect more clouds than sun in the afternoon.  Very windy!

Sunday will be milder. Some cloudiness very early, but clearing for sunshine most of the day.  Still a bit windy, with gusts to 19 mph.  High 61º sd 2.0º
