Area Forecast Discussion National Weather Service Wilmington OH 423 AM EDT Fri Mar 31 2017 .SYNOPSIS... Low pressure will push east across the area this afternoon allowing the chance of showers to persist. Surface high pressure will then build into the region Saturday allowing for drier conditions through the weekend. The chance of rain will then return to the area on Monday. && .NEAR TERM /THROUGH TONIGHT/... Showers continue across the forecast area this morning as low pressure over Indiana approaches from the west. A surface cold front extends south from the low pressure and is currently located just east of the IN/ IL state line. The cold front is forecasted to push through the CWA this morning with the upper level component of the low moving directly overhead. As this occurs clouds will continue through the day along with a chance of showers. PWATs currently greater than 1" will slowly decrease this afternoon towards 0.75" as slightly drier mid and upper level air works into the region. Still with these PWAT values though showers will be possible. The ARW/ NMM/ HRRR and RAP all indicate wrap around showers and have kept PoPs reflecting this thinking. Tonight, low pressure will pull east of the area with weak low level cooling occurring. As this happens moisture will become trapped underneath and inversion allowing extensive low clouds to form. && .SHORT TERM /SATURDAY THROUGH SUNDAY/... These low clouds from Saturday morning will be tough to shake as the pronounced inversion remain into Saturday afternoon. Given the sun angle/ time of year and decreasing low level moisture think we will eventually get sun Saturday afternoon but the process will be slow. 850mb temperatures Saturday afternoon also remain around 2 degrees C and with clouds hanging around think high temperatures will be slow to recover. Most places will be in the mid 50s with slightly higher temperatures across the southwest and slightly lower temperatures across the northeast possible (where clouds will hang around slightly longer). Saturday afternoon surface high pressure will build in from the north but will be weak as the main ageostrophic convergence remains confined to Canada. During the day Sunday surface high pressure will pull east with southeasterly flow returning. 850mb temperatures will climb to near 9 degrees C as mid-level ridging moves overhead. Cirrus will also begin to move in from the west as the next upper level disturbance approaches. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... The 00Z models are in general agreement with an upper level low/trough over the southern plains lifting northeast across the upper Ohio valley Sunday night through Tuesday. There are some differences though on the exact track and timing of an associated surface low that will push up across our region Monday into Monday night. Either way though, this should lead to fairly high pops developing as we head through the day on Monday. Temperatures and any instability will depend on the track of the low. For now will allow for highs in the 60s and limit the chance of any embedded thunder to about the southeast half of our area where the better chance for any instability will exist. Pcpn should taper off from west to east on Tuesday with a brief dry period for Tuesday night into Wednesday morning. However, a broader upper level trough will work its way east and deepen as it moves into the eastern United States through the end of the week. This will bring a chance of precipitation through the end of the long term period and eventually usher in a cooler airmass toward the end of the work week. && .AVIATION /07Z FRIDAY THROUGH TUESDAY/... Surface low pressure is currently located over Indiana this morning with a warm front over northern Ohio. The surface cold front was located back further west near the IN/ IL state border. There is currently ongoing precipitation across all of the TAF sites this morning with thunder being hard to find as instability has waned. The upper level low still west of the region will slowly push east through the day Friday keeping the chance of rain across all of the TAF sites through the day today. Coverage in the showers will slowly decease though as PWATs slowly decline. This evening the low pressure system will pull east with low level CAA working into the region. As this happens models are showing ceilings collapsing. MVFR cigs this afternoon will transition to IFR cigs this evening. OUTLOOK...MVFR ceilings and visbilities possible Monday into Tuesday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
