Area forecast discussion, Jun 29, 6:01 PM EDT, 1 hour 58 minutes before
Area Forecast Discussion National Weather Service Pittsburgh PA 601 PM EDT Sat Jun 29 2019 .SYNOPSIS... Seasonably warm and humid weather with periodic shower and storm chances can be expected through much of next week. && .NEAR TERM /THROUGH SUNDAY/... Changes for the eve update were primarily cosmetic and involved tweaks to POPs based on the latest radar trends. Late day convection will continue to decrease with loss of surface warmth and with eastward progress of weak shortwave support. The actual cold front is still projected to cross the region as the night progresses. && .SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/... A cooler and drier sunday can be expected with sfc high pres under NW flow aloft. Dry conditions will continue Monday as sfc high pressure persists and the upper level ridge axis moves overhead. The first in a series of disturbances will round the periphery of the ridge starting Monday night, allowing for storm complexes to traverse the Great Lakes to move southeast across the Upper Ohio River Valley. Precipitation chances for this period remains low due to the lack of model consensus and the more difficult nature in mapping out storm complex track. && .LONG TERM /TUESDAY THROUGH SATURDAY/... A series of disturbances within NW flow will maintain periodic shower and thunderstorm chances throughout the week. Temperatures will be largely above normal with increased humidity. && .AVIATION /22Z SATURDAY THROUGH THURSDAY/... Eve precip chances will end with passage of a cold front. Models indicate a potential for fog development overnight, but think that enough mixing will continue to preclude much fog development, but this will need to be monitored. .Outlook... A series of disturbances will create thunderstorm chances and their varied restrictions for much of the next work week. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. &&
