AREA FORECAST DISCUSSION National Weather Service Wilmington OH 1239 AM EST Sat Nov 28 2020

SYNOPSIS. After a weak cold front passes tonight, high pressure and dry air are forecast for Saturday into Sunday. Complex low pressure brings the return of precipitation late Sunday through Tuesday, when widespread rain is expected to change to accumulating snow.

NEAR TERM /UNTIL 6 AM THIS MORNING/. Update . Warmed current temperatures a few degrees as the previous forecast was a little cool across the northwest. Otherwise, the forecast required very little adjustments. Cold front is moving across the area with winds shifting to out of the northwest. Low level clouds trailing the front appear rather frail. As a result, mostly clear skies are expected by sunrise, especially across the northwest.


Previous Discussion . Dry weather should continue tonight, with a weak cold front bringing increasing clouds and a wind shift to northwest. Temperatures are forecast to fall to the near normal lower and middle 30s by 6 am.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/. A dry day with abundant sunshine appears very likely for Saturday as an area of high pressure travels up the Ohio Valley. Expect high temperatures reaching the near normal mid and upper 40s Saturday afternoon.

For Saturday night, more tranquil weather is forecast while the high exits to Virginia. Increasing high clouds ahead of the next low pressure should be observed by Sunday morning. Look for low temperatures in the upper 20s to lower 30s early Sunday morning.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. Clouds will increase on Sunday as surface high pressure moves to the east. Highs will range from the lower to mid 50s.

A deepening low pressure system is still poised to affect our region Sunday night into the first part of next week. Models are coming into better agreement in terms of storm development placement and timing. The most difficult part of the forecast is getting the snow amounts down due to several factors.

For Sunday night into Monday, the phasing of two streams of energy, northern and southern, will perturb an area of low pressure over the lower Gulf Coast states. The low is expected to deepen as it move northeast toward the upper Ohio Valley on Monday. As this occurs, initial low to mid level frontogenesis on the back side of the low will rapidly push pcpn northward into our region Sunday night into Monday morning. This period of time is expected to contain the heaviest QPF of the storm system. Pcpn will start out as rain, then it will mix with snow across western locations toward Monday morning as temperatures slowly fall into the mid 30s there. As the low continues to lift northeast through the day, temperatures will show a slow progression downward from west to east as colder air filters into the region. Additional pcpn is expected during the afternoon, but this will be lighter in nature compared to the Sunday night/Monday morning's surge. Using direct model output of snow accumulations with this system can lead one to over forecast snow amounts. Here are the reasons: SLRs will start out around 5:1 and not 10:1; our pavement/ground will likely be warm due to sunshine on Sunday and mild temperatures in the 50s; surface temperatures are not expected to go below freezing until Monday night; the snow will mix with rain at times; the snow falling during the daylight hours with temperatures above freezing will limit accumulations due to a wet/slushy consistency. As such, the first estimates of snow accumulations for Monday look like 1 to 2 inches from east central Indiana to west central Ohio (climatologically favored snowy region) with an inch or less elsewhere

For Monday night into Tuesday, the storm system will undergo occlusion as the surface low and parent mid level low become vertically stacked. Our region will receive wrap around pcpn and lift Monday night, with the pcpn gradually tapering off from southwest to northeast on Tuesday. In addition, the winds will increase, becoming brisk to locally windy. Forecast snow amounts during this period look like 1 to 2 inches. Lows by Tuesday will drop into the mid and upper 20s with little rise expected during the day Tuesday (highs in the lower to mid 30s.)

The storm system will continue to move northeast Tuesday night into Wednesday, allowing surface high pressure to build into our region. After lows in the 20s, highs on Wednesday will range from the mid 30s to the lower 40s.

The remainder of the extended looks complex given the various model solutions on the next upcoming ridge/trough configuration, so there is low confidence in its evolution at this time. Have brought a low chance of rain and snow for Thursday night into Friday as the Ohio Valley may begin to see the influence of a mid level closed low.

AVIATION /05Z SATURDAY THROUGH WEDNESDAY/. Band of clouds will translate across the terminals during the early part of the TAF period. This will bring a period of MVFR ceilings. Once these clouds move out, skies will be clear. Northwest winds less than 10 kt will gradually back through the day and become light southerly tonight.

OUTLOOK . MVFR to IFR ceilings and visibilities as well as wind gusts up to 25 kt are possible late Sunday night into Tuesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
