Fire Weather Discussion

As deepening low pressure stalls to our northeast, wrap-around showers continue to move through the Quad State. Some of these showers include graupel or small hail. Gusty WNW winds today will remain breezy overnight through tomorrow as shower activity slowly trends lesser. There is frost/freeze potential for the end of the week but lingering winds will limit development. The next round of showers and a few storms moves through Sunday with dry conditions Monday.

A Haines Index of 6 means a high potential for an existing fire to become large or exhibit erratic fire behavior, 5 means medium potential, 4 means low potential, and anything less than 4 means very low potential.

Beau’s Forecast Discussion

Good morning, everyone.

We are waking up to some clouds and chilly temperatures.  Clouds are keeping the temperatures from dropping even lower.

Here were the 6 am temperatures.

Clouds will be an issue today.  Some areas with sun this morning will see more clouds this afternoon.  This is all happening around a large upper level low.  Clouds are circulating counter-clockwise around the low.

There is a rain/snow mix to our east this morning.  Portions of Indiana, Ohio, Kentucky, and West Virginia have experienced rain and snow.

We had thunderstorms with hail and graupel in our region yesterday.  Graupel is not the same as sleet or hail.  It is closer to the snowflake family.

There were numerous reports of it yesterday.  There were also numerous reports of pea to dime size hail.  Some lightning, as well.  That was all expected as that upper-level low passed overhead.  Not an uncommon event.

There were several tornadoes Monday and Tuesday.  The NWS continues to do storm surveys.  One tornado struck McCracken County near Woodville.   It was rated EF1 with 90 mph winds.

It was certainly a busy 48 hours for meteorologists.  Two-day events are long.  Thankfully, they do not happen all that often.

The bulk of the rain has moved off to the east of our region, but it is not out of the question that someone could report a sprinkle today.  Rainfall totals would be trace, at most.  Most of the region will simply remain dry.

Any clouds will make it feel cooler with a bit of wind.

Tomorrow into Saturday (during the day) will be dry.  A slow warming trend.

A new weather system arrives Saturday night into Sunday night.  Another system arrives Monday night into Tuesday.  These systems will bring additional shower and thunderstorm chances.  At this time, it does not appear that severe weather will be a concern.  As always, monitor updates.

As far as the eclipse goes, we are concerned about some clouds.  The only question is how much cloud cover.  We will be in-between the Sunday and Tuesday system.

I can’t rule out clouds causing issues with the eclipse.  I will need to monitor clouds.  I currently have the forecast as dry with partly cloudy sky conditions.  Rain chances will hold off until Monday night/Tuesday.

It will warm up this weekend with highs around 70 degrees Sunday and in the low to middle 70s Monday.  Nice spring weather.
