.. Upper Level Low Pressure Storm System Sets Up to our West ..
.. Rain and Thunderstorm Chances Increase ..
On this Tuesday…. a surface high pressure area is the Carolinas eastward over the western Atlantic Ocean. A stationary front extends westward across southern Iowa and northern Kansas and northeast Colorado. As a result of this surface weather pattern, our local surface winds are southeasterly.
In the upper levels of the atmosphere.. an upper level low pressure system is over northeastern Arizona. As a result, our upper air winds at about 18,500 feet are westerly.
A more moist air mass continues to increase its hold on the area.
The upper air low pressure storm system.. currently out to west over northeastern Arizona.. will continue to spin in a counterclockwise rotation with weak disturbances being ejected and then moving northeastward across the state of Texas. As these disturbances approach us, we’ll see increased atmospheric lift with increased cloud cover and rain showers and thunderstorm chances through the balance of the seven day forecast period. With the chance of thunderstorms comes the risk of dangerous cloud to ground lightning. The latest guidance.. from the National Weather Service.. suggests than 1 to 3 inches of rain could fall across our area beginning tomorrow through early next Monday. At this point, no severe weather is expected with this weather system.
Temperatures will be near seasonal averages through the next seven days.
Have a good Tuesday….
