Update on Expected Conditions Overnight/Pre-Dawn Tuesday...

Spotty showers and possibly an isolated thunderstorm cannot be ruled out across the local area through 12 Midnight, but most locations are likely to remain dry based on present indications.

We are monitoring an area of thunderstorms that are continuing to slowly develop along a cool front to the Northwest of the local area. This activity is currently located from near Mason to LLano. If this activity becomes better organized and turns toward the Southeast along the cool front, it could move into at least some parts of the local area toward or after 12 Midnight tonight. In addition...other showers and thunderstorms may also develop across at least some portions of the local area as the cool front moves into the area after Midnight and on into the overnight/pre-dawn hours.

Locally heavy downpours of rain and lightning are likely with any thunderstorms tonight into pre-dawn Tuesday. An isolated stronger storm may also produce gusty winds upon initial approach in some parts of the area as well.

The primary concern for the majority of the local area overnight into pre-dawn Tuesday will be the potential for locally heavy downpours of rain with thunderstorms on at least a scattered basis. Caution is advised if travel is required especially in low lying, poor drainage or other flood prone areas later tonight and into the pre-dawn/early morning hours of Tuesday morning. This would especially be advised during and shortly after any periods of heavy downpours.

Because the pockets of locally heavier activity overnight may remain scattered in nature for much of the area, it is difficult to pinpoint at this time any specific areas that may be more vulnerable to potential low land flooding from localized heavy rainfall. We will continue to evaluate short term trends through the night and issue updates as the situation evolves and becomes more clear.
