A complicated rain forecast is unfolding Wednesday night through the weekend.
The primary concern will be precipitation probabilities at any given point. For now, I have higher chances north of the Ohio River vs south of the Ohio River. I suspect the numbers below will need adjusting as each wave of precipitation passes through the region.

Today through March 15th. Severe weather is not anticipated.

Today’s outlook (below).
Light green is where thunderstorms may occur but should be below severe levels.
Dark green is a level one risk. Yellow is a level two risk. Orange is a level three (enhanced) risk. Red is a level four (moderate) risk. Pink is a level five (high) risk.
One is the lowest risk. Five is the highest risk.
A severe storm is one that produces 58 mph wind or higher, quarter size hail, and/or a tornado.
The tan states are simply a region that SPC outlined on this particular map. Just ignore that.
The black outline is our local area.

Weather Discussion
-
- Dry today into Wednesday afternoon.
- Windy, at times.
- Rain chances Wednesday night into the weekend.
Dry weather today into Wednesday afternoon. There will be some gusty winds developing as we move through the coming days. Wind gusts may top 30 mph from time to time.
Peak winds will be Tuesday into Thursday. If you are boating or burning brush then use extra care.
The winds will increase as the barometric pressure gradient tightens. We call these gradient winds. As pressure tightens, wind fields increase.
This will signal a weather change.
The change will be a frontal boundary that will find itself draped across our region Wednesday night into the weekend. This front will basically stall out over our local area.
Rain chances will be greater north of the boundary vs south of the boundary. That will leave forecasters with one primary question. Where will the frontal boundary stall out? That will be key to rain probability numbers.
This may be a bit of a forecast headache. The front, although it will stall, will likely waver a bit north and south (over time). Thus, monitor changeable rain forecast numbers.
Plan on showers, on our local radars, from Wednesday night into Sunday.
The primary cold front will push across the region Sunday afternoon and night. A band of showers and perhaps a few thunderstorms will accompany the front. I do not expect severe weather. Monitor updates, of course. This is still several days away.
Models do not show high enough dew points for sustained severe thunderstorm activity. They also show the system occluding as it moves across our region. Weakening.
There is almost no CAPE showing up in the models.
There may be some severe storms to our west. The SPC is forecasting that and I can’t disagree. For now, however, I do not see a risk locally.
Let me show you some of the forecast rain totals from different models and the NWS.
WPC/NOAA rainfall totals forecast through Monday.
.
EC model rainfall forecast totals through Monday.
.
GFS model rainfall forecast totals through Monday.
We do have a risk of flash flooding Thursday/Thursday night.
The WPC has placed us in a low-end risk of excessive rainfall.

Again, as a reminder, these are models. They are never 100% accurate. Take the general idea from them.
What should I take from these?
- The general idea and not specifics. Models usually do well with the generalities.
- The time-stamp is located in the upper left corner.
- The EC European weather model is in Zulu time.
.
What am I looking at?
You are looking at different models. Meteorologists use many different models to forecast the weather. All models are wrong. Some are more wrong than others. Meteorologists have to make a forecast based on the guidance/models.
I show you these so you can see what the different models are showing as far as precipitation. If most of the models agree, then the confidence in the final weather forecast increases.
