Area forecast discussion, Jul 28, 3:09 PM EDT, 58 minutes before
Area Forecast Discussion National Weather Service State College PA 309 PM EDT Fri Jul 28 2017 .SYNOPSIS... Low pressure system will pass to the south of the state tonight and push off the coast early Saturday. Behind this system, high pressure over Great Lakes will build into the region into early next week. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... Heavy rain in showers now covers most of the southern tier. Right in place as they should be/have been expected. PWATs are near 1.5 in the central Cos and slightly over 2" in the S - where it has been raining for a few hours already. Flash flood watch is well- placed. Not much time for more thoughts. Flood threat is high, but the precip should be much lighter north of I-80 and some northern tier locations may stay totally dry. River flooding generally not expected, but some of the smaller tribs to the Juniata and Lower Main Stem Susq need to be watched closely. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/... Dry air at the sfc makes a quick entry from the north on Sat as the low pressure deepens to our south. Any showers in the morning in the srn tier should slink off to the SE. Will linger a small chc for the lower Susq into the aftn. Temps will be chillier than normal, but perhaps not quite record mini-maxes. && .LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/... Weather highlights during the period look rather benign in the wake of rare July rainstorm more reminiscent of the cool season. Light rain is still expected to clear out of the far southeast counties by early Saturday night. High pressure and accompanying push of abnormally dry/below normal PW air will work into the area by Sunday with dry and pleasant wx continuing early next week. Sunday morning minimum temps should feel refreshingly cool in the mid 40s to mid 50s. Air/water temperature spread should promote valley fog especially over the northwest Alleghenies. Looking ahead into next week, the models and ensemble means show good consensus in depicting a persistent/deepening mean trough over the eastern U.S. in response to strong/amplifying upper ridge centered over the Great Basin. A stray shower to T'storm is possible Tue-Wed as subtle shortwaves rotate ahead of the main trough axis and warmer temperatures and higher dewpoints return to the area. A signal is emerging in the latest guidance for an increasing risk for showers/storms during the second half of the week as a front progresses east from the northern Plains. Temperatures should trend warmer Sun-Tue and peak a few degrees above early August climo values in the warm sector around midweek. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... Mostly VFR at 19Z. However, widespread SHRA/TSRA over the srn tier will eventually spread into the terminals. Have made mentions of TS in most of the TAFs except BFD. Heavy rain and poor vis/cigs are poss even in showers without thunder. Have mentioned very little IFR for now, and will allow for more specificity in the fcst for >6hrs. Dry air does work down from the N early tonight in the nrn tier, and in the morning in IPT/UNV/AOO. MDT and LNS will have showers linger longest into Saturday - perhaps even into the early aftn. Dry wx with no restrictions should start late Sat. .OUTLOOK... Sun...FG/low cigs poss AM. Otherwise no sig wx. Mon-Wed...No sig wx. && .CTP WATCHES/WARNINGS/ADVISORIES... Flash Flood Watch through Saturday afternoon for PAZ024>028- 033>036-056-057-059-063>066. && SYNOPSIS...Dangelo NEAR TERM...Dangelo SHORT TERM...Dangelo LONG TERM...Steinbugl AVIATION...Dangelo
