AREA FORECAST DISCUSSION National Weather Service Wilmington OH 1112 PM EDT Sun Sep 19 2021
SYNOPSIS. An upper level disturbance will lift north across the Ohio Valley overnight into Monday, bringing a chance for showers and a few thunderstorms. Widespread showers and a chance of thunderstorms will be possible Tuesday into Wednesday as a strong cold front moves through the area. Behind the front, a much cooler airmass will settle into the region through the second half of the week.
NEAR TERM /THROUGH MONDAY/. Mid level ridge stretching from the Great Lakes into the Mid Atlantic region will continue shifting east with flow backing southerly. Short wave energy will lift north into the lower Ohio Valley tonight into Monday morning. A southerly low level jet of 25 to 35 kts will aid moisture in advecting north into the region. In the developing southerly flow, moisture will be on the increase with precipitable water values increasing to 1.75 to 2 inches across the west. This increased moisture will lead to showers and a few thunderstorms overnight into Monday morning -- with the main area of pcpn along and west of the I-75 corridor. Have pops increasing to likely in the far west by 12Z Monday. In the moist environment lows will be in the mid and upper 60s.
SHORT TERM /MONDAY NIGHT/. Fairly widespread showers will likely be ongoing across western portions of our area Monday morning, but as the main short wave lifts north into Michigan, we may see a bit of a decreasing trend in coverage later in the morning and into early afternoon. That being said, some additional mid level energy will continue to lift northeast across the region through the afternoon, keeping a chance of showers and a few thunderstorms persisting across the area. Will then hang on to a chance for some showers through Monday night as we remain in a moist/higher PW southwest flow pattern.
Expect the coolest temperatures on Monday to be across our west, where pcpn and lower clouds will be more prevalent. Will range highs from the mid/upper 70s west to the lower 80s in the east. Lows Monday night will be in the mid 60s.
LONG TERM /TUESDAY THROUGH SUNDAY/. Active weather pattern to begin the extended period as a sharp cold front pushes west to east through the Ohio Valley. Interestingly, there is still significant uncertainty with the upper pattern during this time, with the GEFS barely closing off an H5 low over the central Great Lakes before lifting it to the northeast on Thursday . while the EPS still shows a more significant closed H5 low.
Based on the overall trend toward the deeper Euro solution, QPF has increased through mid-week with totals in the 2-3 inch range Tuesday and Wednesday, with heaviest rainfall potential late Tuesday through early Wednesday along the cold front. Therefore have added heavy rain/localized flooding potential to the HWO. Also wind field has stiffened behind the front, so grids now include 25-30 mph northwesterly gusts Wednesday evening.
Thursday is looking to be a cloudy chilly day. High temperatures have trended downward with each of last several model runs . with current forecast holding temperatures in the 50s to low 60s all day. Upper low lifts northeast Friday, providing a period of dry weather, before a reinforcing trough digs into the Great Lakes again on Saturday.
AVIATION /03Z MONDAY THROUGH FRIDAY/. Mid level ridge over the area to shift east as flow backs southerly. Short wave energy will lift north into the lower Ohio Valley tonight into Monday morning. Increasing southerly flow ahead of this will help spread moisture north into the region. This increased moisture will lead to showers and a few thunderstorms overnight into Monday morning.
Favorable moisture and lift will generally affect areas along and west of I-75. VFR ceilings will also gradually lower tonight into Monday morning. Some MVFR cigs will be possible early Monday, but the best chance looks to occur west of the TAF sites so have maintained a VFR forecast.
OUTLOOK . MVFR ceilings, visibilities, and thunderstorms possible Monday night and Tuesday. MVFR/IFR ceilings and visibilities likely Tuesday night into Wednesday.
