... Colder and windy today behind a departing front. High pressure brings dry weather this weekend, with a warmup. Showers return by mid week.
NEAR TERM /THROUGH TONIGHT/... As of 200 AM Friday...
Cold frontal boundary at 07Z is currently across southeast Ohio, and will continue to sag south across the area, generally to the east of the CWA by early to mid morning. Light snow showers can be expected, mainly across our north and east, as evidenced on radar, with frontal passage and in some brief upslope activity across higher terrain. Flurries will also be possible outside of the brief snow shower activity through this morning. Little to no snow accumulation is expected across the lowlands, with generally less than an inch across the northern mountains.
Biggest factor today and tonight is the colder air that will filter into the area, along with gusty winds in CAA/increased pressure gradient. After an initial drop in temperatures early this morning, expect only a slight rise during the day. Saturday morning will be quite cold as of late, with surface high pressure centered across the area.
Still expecting wind advisory conditions across the higher terrain of the northern mountains taking hold today and lingering into Saturday morning. Current headline area and timing look good.
SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/... As of 400 AM Friday...
* High pressure brings dry and warmer conditions this weekend into early next week.
After a cold dip in temperatures, warmer trends return Saturday afternoon with southerly flow on the back side of an exiting ridge. The region should see a short sunny break before clouds begin to stream back across Saturday afternoon and evening. Afternoon highs slowly climb into the upper 30s to lower 40s. Overnight temperatures will not be as bitter as the previous night with lows in the 30s across the lowlands and in the 20s along the mountains.
On Sunday, the upper level subtropical jet takes control overhead bringing mild temperatures for the start of the week. Temperature trends will be similar Sunday and Monday with highs in the 40s and 50s, coolest along the mountains. Overnight temperatures will be slightly cooler Sunday night with lowlands expected to be above freezing Monday night as the next surge of warm air moves out of the southwest.
LONG TERM /TUESDAY THROUGH THURSDAY/... As of 400 AM Friday...
* Next chance of precipitation Tuesday/Wednesday.
A deepening trough across the southwestern states on Monday will bring an active wet pattern back to the region on Tuesday. There is still a bit of uncertainty on how quickly the first wave of precipitation moves up, with high uncertainty for the multiple waves that follow. Generally, next week will be warmer than normal with wet conditions as the subtropical jet sends several systems out of the deep southwest.
