Update... 
issued at 707 am EDT Thursday may 23 2013 


Areas of dense fog...which have been prevalent across the area during 
the overnight hours is starting to lift. Will mainly freshen up the 
hourly temperatures...dew points...and sky cover to better jive with 
the latest observations. 


&& 


Short term...(today through friday) 
issued at 340 am EDT Thursday may 23 2013 


An upper level trough currently traversing the western Great Lakes 
region will move through the commonwealth late this afternoon. 
The combination of heating and forcing associated with this feature 
will initiate another round of scattered to numerous showers...along 
with a few thunderstorms across the area this afternoon. Highs will 
be more seasonable today...with middle to upper 70s for most locations. 


The shower activity will gradually wind down tonight from west to 
east as much cooler and drier air advects in behind the departing 
trough. Low stratus will likely set in overnight with the low level 
flow out of the northwest. Lows will bottom out in the upper 40s to 
around 50 degrees. 


Friday will feature a beautiful day...with mostly sunny skies and 
highs topping out in the middle to upper 60s. 


Long term...(friday night through wednesday) 
issued at 438 am EDT Thursday may 23 2013 


A surface high pressure ridge passing across the region underneath 
northwest flow aloft will bring a dry and cool air mass to start 
the time frame. This should allow for unseasonably cool 
temperatures...with valleys dipping into the 30s early Saturday 
morning. 


As time GOES by...the cool and dry air mass will slowly depart to 
the east and a warm front will approach from the southwest. This 
boundary coinciding with the edge of a subtropical ridge creeping 
eastward will pose a threat of showers/thunderstorms. The GFS and 
European model (ecmwf) do not agree on the timing of this...with the GFS being further 
northeast. Have used a generalized approach at this point...granting 
credence to both solutions and using 20 percent probability of precipitation each period from 
Monday on.

Aviation...(for the 12z tafs through 12z Friday morning) 
issued at 707 am EDT Thursday may 23 2013 


LIFR fog and stratus will burn off in the next hour or so. A cold 
front will move through during the day...with some scattered to 
numerous showers expected as well as an isolated thunderstorm. Do not 
expect these to be particularly heavy and will forgo having any MVFR 
restrictions. Winds will shift to the west and could gust in the 15 
TI 20 knots range during the afternoon. MVFR stratocu will build in 
tonight...which may eventually descend to IFR status towards dawn.

Jkl watches/warnings/advisories...
