AREA FORECAST DISCUSSION National Weather Service Wilmington OH 411 PM EST Mon Jan 25 2021

SYNOPSIS. Low pressure will move up the Ohio Valley tonight and slowly depart the region on Tuesday. A cold front trailing the low will swing across the area late Tuesday into Tuesday night. Another low pressure system will pass south of the area Wednesday afternoon and night.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Radar imagery shows that precipitation is exiting the forecast area except for far southern counties. That area will see rain continuing through the rest of the afternoon and evening. Elsewhere, expect precipitation to redevelop ahead of mid level forcing and spread across the region. This will likely not be as widespread as what occurred during the day. Precipitation type will still be problematic as surface temperatures have been struggling to rise and there is considerable uncertainty how quickly that will occur given sub optimal surface temperature forecasts from just about all guidance.

While highway temperatures are above freezing, secondary roads may not be as warm. In addition, as we lose incoming radiation with sunset, there is the potential for more slick conditions with the additional precipitation. Given uncertainties, opted to extend the advisory and be generous with valid time. Most likely, this will be able to be cut back or cancelled before expiration.

Slow rise in temperatures will occur through the overnight.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. Surface low will be moving away from the area. But boundary trailing this low will extend across northern Ohio and Indiana. This will swing southeast across the region late Tuesday into Tuesday night. Expect some precipitation along and south of the boundary. At this point felt that this only warranted low chance PoPs and it should be warm enough for precipitation to be rain. Temperatures will be above normal with highs ranging from the mid 30s to near 50 and lows in the mid 20s to lower 30s.

LONG TERM /WEDNESDAY THROUGH MONDAY/. H5 ridging and weak surface high pressure are in place across the Midwest Wednesday morning. Higher RH in the low to mid levels will keep a blanket of clouds draped across the fa throughout the day. Combined with northerly surface flow, temperatures will remain near seasonal norms in the lower to middle 30s.

The progressive H5 flow pattern will swing a s/wv trough through the area late afternoon on Wednesday. A vort max embedded in the trough will traverse through the Tennessee Valley, keeping the best forcing south of our fa. However, counties along and south of the Ohio River still appear to be in a favorable position to receive and accumulate snowfall during the evening/overnight. While counties further east have a better chance for snow to accumulate due to the later onset time (having colder surface/pavement temps), minor travel impacts during the evening rush may still be a concern for locations near Cincinnati. The Euro and hi-res NAM appear to favor a more northerly trend with this snowfall, allowing for light accumulations to occur up in central/west-central Ohio, while the operational NAM/GFS keep this snow mainly south of I-70. Regardless, it does appear that counties along and south of the Ohio River will observe rapid accumulations of up to 1.0-1.5" Wednesday night. A few ensembles do show accumulations possible near Advisory criteria, but more clustering occurs near 1.0" of snow, so went with that trend for now in the grids. A general trend towards lower PoPs and light snow accumulations will be observed north of the Ohio River for Wednesday night, but a light coating of snow in west-central Ohio cannot be completely ruled out.

Precipitation chances will quickly diminish by Thursday morning as the s/wv trough is ejected eastward and replaced by another H5 ridge. This ridging pattern and surface high pressure looks to keep conditions dry through the end of the work week. While below seasonal temperatures in the middle 20s to lower 30s on Thursday are expected, a subtle warming trend will ensue with the ridging pattern as we head into the weekend.

Models have been consistent in showing a low pressure system from the lower Plains impacting our fa Saturday night into Sunday, so kept the trend of likely/categorical PoPs in the grids for that period. The current forecast does have snow mixing in across much of our northern half of the CWA, especially Saturday night, but uncertainty remains on snow accumulations this far out in the period. A warmer air mass in place near the beginning of this event may allow for rain to be the predominant hydrometeor type (with a transition to all rain likely during the day Sunday), but this system will be something to keep an eye on due to high likelihood of pcpn occurring.

AVIATION /21Z MONDAY THROUGH SATURDAY/. Precipitation has ended at most terminals. But expect that to be short lived with additional precipitation developing by 00Z. Surface temperatures will be slow to warm, but should eventually rise enough to change precipitation from freezing rain to rain. Precipitation will come to an end area wide between 02Z and 06Z.

IFR to LIFR ceilings will prevail through most of the period. Expect ceilings to fall below alternate minimums except perhaps at KCVG. Some slight improvement in ceilings is forecast late in the TAF period.

OUTLOOK . MVFR ceilings will likely persist into Wednesday night. MVFR/IFR visibilities possible again Wednesday afternoon and evening.
