Warm and mainly dry weather is expected with building high pressure early this week. The passage of a mid week cold front should return seasonal temperatures to the region. && .NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
With 8:45am update, made minimal changes to hourly temperature trends. Also removed all chances of rain in the morning, both north of I-70 and south of I-80. Chance pops were maintained for northern WV and MD this afternoon as the boundary and diurnally driven instability could result in a few showers or thunderstorms. Highs are still expected to be around 5 degrees above average, though dew points should slowly fall through the day behind the boundary.
