... Dry weather and seasonable temperature can be expected for the remainder of the week under high pressure.
NEAR TERM /UNTIL 6 AM THIS MORNING/... Mid level clouds will continue west of I 77 through the night; otherwise, most areas will be generally clear with building high pressure under continued, cold, nnwly flow aloft. Under this pattern, seasonably cold overnight lows in the 30s can be expected.
SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY NIGHT/... High pressure will remain in control during this period, as a blocking ridge over the Mississippi and lower Ohio Valleys will keep troughing bottled up over the Rockies and northern Plains. Plenty of sunshine is figured for both Thursday and Friday. Temperatures will remain seasonable, with 500 mb heights only starting to rise on Friday.
LONG TERM /SATURDAY THROUGH WEDNESDAY/... The upper ridge axis finally makes some eastern headway in the extended period, arriving in our area Saturday. This will mark the start of a period of above-normal temperatures, with readings 10 to 15 degrees above normal by early next week.
Dry weather continues Saturday. A shortwave trough will knock down the ridge somewhat Saturday night and Sunday, pushing a weak front across as well. With overall weak forcing, minimal PoPs were maintained. Better rain chances arrive for the first half of next week, as the next shortwave may set up a better moisture tap from the southwest. Still, with the midlevel flow remaining zonal or as flat ridging, significant rainfall is not anticipated.
