MESSAGE 1’S WILL BE ALLOWED TO EXPIRE AT 10:00 PM TONIGHT
Message 1’s will be allowed to expire at 10pm tonight as the threat of heavy rainfall has come to an end.

Storms today remained weak over the District with a few very strong storms to the north and just east of the District boundary. Storms have since moved well eastward and onto the eastern plains. A slight chance for a few isolated showers this evening before skies clear out overnight. Any shower activity this evening will remain minimal. Temperatures will drop into the upper 50s to low 60s overnight.

A change in the pattern tomorrow as a cold front brings much cooler conditions throughout the day. A good chance for increasing clouds with a few showers ahead of the cold front during the morning tomorrow. This cold front will move in from the N/NE before, or right around midday. Shower activity and strength will hinge heavily on daytime temperatures tomorrow, mainly due to the timing of this cold front.
STORM RAINFALL POTENTIAL AND DURATION: Typical showers will produce a trace-0.10" total in 10-30 minutes.

WORST CASE SCENARIO: A moderate to strong thunderstorm will produce rainfall rates of 0.10”-0.30” total in 10- 30 minutes.
