NWS Wilmington, OH wrote its last area forecast discussion before the first event at May 14, 2:59 PM EST, 2 hours 1 minute earlier.
AREA FORECAST DISCUSSION National Weather Service Wilmington OH 359 PM EDT Sat May 14 2022 .SYNOPSIS... Active weather pattern this weekend with scattered showers and storms into this evening and again Sunday night. Slightly cooler and drier air filters in for the start of the workweek before additional chances for storms arrive midweek and beyond as warmer and more humid air returns to the area. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Diurnal heating combined with some increase in low level moisture has result in moderate instability across the area this afternoon. Mid level support is limited with rather light wind flow indicated on area soundings. Disorganized -- slow moving storms to continue into this evening. Storms to our west, showing a little better organization invof of a weak front to work into west central Ohio and then weaken with the loss of heating. DCAPE values up to 1000 J/KG. Given the lack of favorable wind flow for good organization -- the main threat will be strong to damaging winds, heavy rain due to the slow movement and some small hail. The airmass will quickly stabilize by late this evening with convection weakening and shifting southeast of ILN/s area. Some clearing is expected late which could lead to the some patchy fog development. Lows tonight to range from the upper 50s to the lower 60s. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... Mid level shortwave to dig southeast from the northern plains across the Mid MS Valley Sunday and into the Great Lakes Sunday night. In warm sector moderate instability develops Sunday afternoon but favorable forcing is not present. Some of the forecast soundings indicate a cap that may inhibit convective development during the daylight hours. Have limited any mention of thunderstorms to slight chance late in the day. Have opted to go a little warmer than NBM guidance for highs. Expect warm highs in the lower and middle 80s. Favorable forcing and deeper-layer shear develops late Sunday evening into the overnight hours, as the shortwave approaches from the west. Have increased pops to categorical for the most favored time for storms late evening/overnight. Uncertainty exists regarding the amount of instability that will remain and the potential for strong to severe storms. Forecast soundings are showing a near-sfc inversion, and elevated instby by the time the most favorable lift comes into play. This will work to limit severe potential. Will continue to mention this potential with the best chance in our far west as convection weakens as it tracks across ILN/s FA. && .LONG TERM /MONDAY THROUGH SATURDAY/... On Monday morning, a surface cold front will be moving southeast through the ILN CWA, as the axis of a mid-level shortwave will already be just past the forecast area. The main period of convective potential will already be done by 12Z, but until the surface front has passed, there will still be some chance of showers for the area -- ending west-to-east through the morning and early afternoon. NW flow behind the front will advect in a drier and cooler air mass, with skies eventually clearing during the day. Despite the change in air mass and the NW winds, temperatures will remain close to normal, with highs in the lower to mid 70s. Some gusts to around 20-25 knots look possible, so winds are slightly higher than the model blend. A flatter mid-level pattern will set up across the Ohio Valley going into the middle of the week, while a broad area of surface high pressure will gradually drift eastward on Tuesday and into Wednesday. This will keep surface flow light and generally with a northerly component, so temperatures will likely only change slightly in the Mon-Tue-Wed time frame -- still remaining in the 70s. The situation aloft will be a little different, as the axis of a ridge begins to move into the area, and some theta-e advection at 850mb and above begins as early as Tuesday night. More robust moisture advection will pick up at lower levels on Wednesday and into Wednesday night, with some kind of west-to-east boundary establishing itself across the Ohio Valley. As this setup combines with some fast-moving shortwaves moving across the region, atop a low-amplitude southeastern ridge, occasional shower/storm chances are expected from late Tuesday night through the end of the week. With a fast-moving upper pattern and multiple shortwaves, confidence in exact timing for the highest precipitation chances is uncertain, though it appears some of the higher chances may be on Wednesday night. It is also uncertain if there will be a favorable overlap of shear and instability during this time period, but it appears possible, especially as SBCAPE begins to ramp up on Thursday. Thus, this period will need to be watched for some strong storm potential. The stronger surface-based warm advection beginning on Thursday will continue into Friday and Saturday, as deep-layer southwesterly flow sets up over the ILN CWA. This looks like it may lead to diminishing precipitation chances from Thursday to Friday to Saturday, as the pattern becomes one that supports temperatures rising above normal. In fact, the strength of the flow supports a forecast a little above the model blend, and max temps were increases lightly for all three days from Thu-Fri-Sat. Mid to upper 80s are expected Friday and Saturday, with an outside chance at some 90 degree readings in the southern part of the forecast area. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... Moderate instability resulting in scattered thunderstorm development in the warm air mass this afternoon. Storms will be disorganized due to the light flow. A few of the storms could produce gusty winds. Have generally covered these storms with VCTS with a tempo at KCVG and KLUK where coverage is better. Visibilities will be reduced to IFR in heavy downpours. Convective activity will be tapering off slowly past sunset with loss of diurnally-driven instability. Any spots that are impacted by SHRA/TSRA will be susceptible to BR/FG development late tonight as skies clear. Have MVFR vsby restriction at KLCK and IFR at KLUK. Any fog will improve quickly Sunday morning with VFR conditions expected thru most of the daylight hours. OUTLOOK...Thunderstorms are possible Sunday night. && .ILN WATCHES/WARNINGS/ADVISORIES...
