Slapped Back To Reality

After skipping from January to May yesterday, the region falls back to January with a slap of winter reality thanks to this morning's rude visit from a noisy rainstorm and cold front.  Temperatures are at their warmest points of the day early this morning and likely will be a bit colder on the drive home tonight as strong, gusty winds from the west pull colder air back into the region.

Hope you enjoyed your fling of Spring yesterday!

The temperatures modeled above are from the raw version of the high resolution NAM for this afternoon -- generally showing 30's overspreading the region.  The model might be a bit fast shoving 30's back in our face but I do foresee a gradual cooldown through the course of the day, with temperatures by midday in the mid 40's around Philly, around 40 for the drive home with 30's likely to the north and northwest of Philadelphia.  If we see a bit more sunshine around we might nudge up an extra degree or two but clouds and sun will mix at a 50/50 or slightly greater lean towards clouds through the day.

West winds will gust upwards of 40-45 mph around the region and be sustained at 20-30 mph for much of the day.  The relative lack of wind out there in Eastern Pennsylvania this morning will give way to increasing winds as the push of cold from the west takes over.  Wind chills will feel several degrees colder.  A flurry can't be ruled out north of I-78 either later this afternoon.
