Would not be surprised if there was a bit of a squall that pops tomorrow afternoon across PA and MD. High res and NAM is sorta nudging in that direction. Timing would be 3-6 across PA?

If we can pop some sun in the afternoon the odds for that would probably go up a fair bit.

weather for dummies....will my Pocono snow at Jack Frost Mountain (Lake Harmony/Blakeslee) all melt away with this rain threat? This weekend is Ski for the Cure?

Not sure of the base at Jack Frost but I would imagine it'll take a bit of a beating over the weekend. Temps won't get as high there as here in Philly so carnage won't be as bad as Spring Mount and the local hills face...

TU drexel hill on the threads. on wind...imo this will be significantly worse between noon and 9 PM Friday...convective gusts of 50-60 knots appear realistic in the lines of remaining midday/aftn instability. everything i am seeing thru the 18z runs from tghe ec/gfs/nam says tstms with svr wind. then i think we will see a few minutes of nw gusts of 45 to 55 kts at many locations along and se of I95 between 4 pm and 7 P as the strong cold front pushes thru with asstd 10mb pres rises in 3 hrs and temps dropping 10-18 degs within an hr. presuming this expectation of convection and momentum transfer is correct...then it will be notably MUCH stronger than last saturday with resultant many trees and wires down with asstd power outages. the rest you can conjecture. this is based on hi wind composites/transfer programs/richardson numbers and internal mxg ht gust transfer tools. liklihood for convection between noon and 5P and I think PHL will have its strong cfp ard 5PM... am going to lower temps susbantially at 7 pm tomorrow. the warmer its is above MOS guidance during midday tomorrow the stronger the wind. wd

I was merely going off the graphical forecast plots issued by mt holly. The wind gusts aren't forecasted to be as strong as what they were showing last saturday. But yea i said that in the wind/svr weather thread, that if we can get some tstorms those strong winds could easily be brought down. The 850 winds are ripping at 105 mph...925 mb winds are between 70-80 mph.
