… Cold Front Passes Wednesday and Again on Friday …
… Limited Rain Chances with Wednesday Cold Front …

On the Weather Map…

On the surface map… surface high pressure is over south Texas and the northwest Gulf of Texas. A low pressure area is over South Dakota with a cold front extending southward into northwestern Kansas then southwestward into southern Colorado and southern Utah. As a result of this surface weather pattern, our surface winds are light and variable.

On the upper air map… a trough, or line, of upper level low pressure is located over the Ohio and Tennessee Valley regions and covering the eastern half of the USA. Another upper level low pressure disturbance is located over the western Dakotas and eastern Montana and eastern Wyoming. As a result of the upper air weather pattern, the 30,000 foot winds over our local area are northwesterly 70 to 80 mph.

What I am Seeing As I Look Ahead…

The surface high pressure area and its associated clockwise wind flow, which is centered overhead, will move east of the area later today into tonight with the return to southerly surface wind and some increase in low level moisture and maritime tropical air off the Gulf of Mexico.

Tomorrow, 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 by afternoon tomorrow with the upper air low pressure disturbance being a little slower in crossing over the area. While the system will be pretty dynamic, I still have real doubts about how much gulf moisture will be able to return in advance of the system so I will post only slim rain chances for tomorrow into tomorrow night, first associated with the front moving southeastward, and afterwards into tomorrow 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.

Surface high pressure will once again move east of the area by late in the weekend into early next week with low level moisture, off the Gulf of Mexico, making a return to the area.

Have a good Tuesday..
