000 FXUS61 KPBZ 230543 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 143 AM EDT Sun Apr 23 2017 .SYNOPSIS... High pressure should maintain dry weather today. Low pressure tracking toward the Southeastern United States will result in rain chances for areas southeast of Pittsburgh for the start of the new work week. && .NEAR TERM /THROUGH TODAY/... High pressure should result in dry weather today as an upper low deepens across the MS/TN Valley regions. More clouds are expected S of I 68 on the nrn periphery of the deepening low. Temperatures are expected to average near seasonal levels. && .SHORT TERM /TONIGHT THROUGH TUESDAY/... Meanwhile, the southern low is forecast to dig toward the Southeastern CONUS before progressing up the East Coast during the first half the week. This scenario should confine rain chances to the I 68 vicinity, and over the ridges and eastern CWA periphery during the period. Seasonably cool temperature will begin to moderate by Tuesday as heights rise in response to Western Conus troughing. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... Temperature is progged to rise 10 to 20 degrees above average for the latter half of the week as flow amplifies as broad, cold low pressure develops over the western CONUS. Shortwave energy and resulting moist southwest flow aloft will fuel rain chances, best potential for which currently looks to be on Wednesday night with the crossing of a negatively tilted trough axis. && .AVIATION /06Z SUNDAY THROUGH THURSDAY/...
