… A Mostly Dry Weather Pattern Ahead over the Next Seven Days …
… Cold Fronts Pass Early Wednesday and Again on Friday …
… Limited Rain Chances with Wednesday Cold Front …

On the Weather Map…

On the surface map… a cold front extends from a surface low over southern Kentucky through Tennessee then into western Georgia then the Florida panhandle into the central Gulf of Mexico where it becomes stationary and extends westward into northeastern Mexico. Surface high pressure, behind the front, extends from Kansas into west Texas. As a result of this surface weather pattern, our surface winds are west northwesterly.

On the upper air map… a series of upper level low pressure disturbances is embedded in a rather zonal (west-to-east) wind flow over the USA. The first disturbance is centered over western Tennessee and western Kentucky with another strong disturbance over western Montana and Idaho. As a result of the upper air weather pattern, the 30,000 foot winds over our local area are west northwesterly about 110 mph.

What I am Seeing As I Look Ahead…

In the wake of our cold front late Saturday night, a dry and stable weather pattern with plenty of sunshine and less humid conditions prevails over our area with the start of the new week.

By tomorrow, the surface high pressure area and its associated clockwise wind flow will move east of the area with the return to southerly surface wind and some increase in low level moisture and maritime tropical air off the Gulf of Mexico.

Late Tuesday night into early Wednesday, a passing upper air low pressure will move from northwest to southeast across north Texas and Oklahoma. An associated cold front will move across the area on Wednesday morning with the upper air low pressure disturbance being a little slower in crossing over the area. While the system will be pretty dynamic, I have real doubts about how much gulf moisture will be able to return in advance of the system so I will post only very slim rain chances for Wednesday, associated with the front moving by, and afterwards into Wednesday night as the upper air system completes its passage overhead.

A more stable weather pattern will prevail for the latter party of the week through the upcoming weekend. Another cold front will pass on Friday but it will only reinforce the air mass in place. Little in the way of sensible weather, other than a wind shift, is expected with the front on Friday.

Have a good Monday..
