Rain for the Weekend!

Current Conditions:
The current temperature as of 4:53 P.M. is 87 with clear skies and winds out of the south at 17 mph with gusts up to 23 mph.  Currently there is a negatively tilted trough located over Nebraska, Wyoming and South Dakota with the trough axis stretching from Nebraska down into Mississippi.  This is causing a broad area of divergence over our area.  Moisture at 700mb is aiding in our chances to see showers this afternoon and this evening.  The moisture is present because the winds are out of the south bringing with it moist Gulf of Mexico air.  At the surface, the center of low pressure is located over South Dakota with another center of low pressure over Kansas.  The cold front stretches from South Dakota down into Texas.  High pressure which has been dominating our area for the past few days is located over Pennsylvania.  Due to the divergence aloft and the available moisture, this is why a shower chance still exists this afternoon and tonight.

Surface Map valid for 1:00 P.M. on Thursday, May 30, 2013.

Forecast Discussion:
The trough that is currently located over Nebraska, Wyoming and South Dakota will push east tomorrow keeping us in the divergence area of the trough.  Winds will remain out of the south tomorrow bringing with it the warm, moist Gulf of Mexico air allowing for pop-up showers to occur tomorrow afternoon.  The best chance of rain will occur Saturday night into Sunday morning as a cold front moves through the area.  Isolated storms may develop Saturday afternoon with some becoming severe.  The morning low for tomorrow will be 71 and the high will be 85 with winds out of the south at 14 mph with pop-up showers possible after 1:00 P.M.

Saturday:  High 86  Low 70  winds out of the south at 14 mph with pop-up showers in the afternoon with some severe storms. Chance of precipitation is 40%.  Chances increase later Saturday night as the cold front moves through at midnight.

Sunday:  High 75  Low 61 winds out of the northeast at 5 mph.  Rain showers in the morning as the front moves through with showers ending by 12:00 P.M.  Chance of precipitation is 75%.
