2/18/2009 @ 7:00 AM in Bedford County, Tennessee

I never heard any thunder last night and this morning most of the activity has moved to our East except for a few spotty areas of lingering showers. The Barometer is low this morning and has not shown any indication of rising yet. There is a Frontal boundary that will pass through Middle Tennessee later this morning or possibly early afternoon. The heating of the day associated with the cooler air behind this front could set up a squall line bringing us a round of Thunder Storms with Hail and strong Gusty wind. This line should move quickly and I don’t see a wide scale severe weather outbreak associated with this. However in places it could be bumpy for a little while. After all of this moves past tomorrow looks to be Fair but cooler. Now for the facts.

The Temperature at 7:00 is 51 degrees, warm for mid February and we should see 65 before the Front comes in. The Low tonight with still cloudy sky looks like mid 30’s.

Barometer is 29.70″ and Steady. This instability will aid the development of some Storms when the front passes, the warm temperature will help that as well. Look for a rise in pressure behind the front. We should be well above 30.00″ on Thursday.

Humidity is a damp 98% but will dry out tonight and tomorrow.

Wind is South at 7 this morning, after a bit of a gusty night. Look for some gusty winds today and a shift to the North, still breezy tonight.

Sky is overcast today and will continue so through tonight. Clearing on Thursday.

The Forecast Summary for today is Cloudy and mild with scattered showers this morning. A possible line of Storms in the early afternoon then cooler. High 66 and Low of 35 tonight. Slight chance of severe weather this afternoon so mind the NOAA weather radio. Thursday looks to be seasonably cool and clearing.

This just in from the NWS.

WARM, MOIST AIR WILL ADVECT INTO MIDDLE TENNESSEE DURING THEMORNING AND EARLY AFTERNOON. A COLD FRONT IS EXPECTED TO PASSTHROUGH THE MID STATE DURING THE AFTERNOON, AND MAY PRODUCE A LINEOF THUNDERSTORMS. IT IS POSSIBLE THAT A FEW OF THESE STORMS COULDREACH SEVERE LIMITS, WITH LARGE HAIL AND DAMAGING WINDS BEING THEPRIMARY THREATS, MAINLY IN AREAS SOUTH OF INTERSTATE 40.

So this is 2 Bumpy Wednesdays in a row, hope this is not a trend.
