Update on expected rain event for mainly Tuesday night into Wednesday...




Changes Since Last Update:
  • No major changes have been made; attempted to continue to better define various timing elements where possible

Valid time of Advisory:
06:00 AM Tomorrow until 10:00 PM Wednesday (03/28/18)


Expected impacts:
  • Scattered showers are possible during the daytime hours on Tuesday - and an isolated thunderstorm cannot be completely ruled out on Tuesday
  • Periods of showers and thunderstorms are likely during the pre-dawn and morning hours on Wednesday (i.e., from 5am-12 Noon on Wednesday)
  • Locally heavy downpours of rain are possible during periods of thunderstorms, especially from 5am to 12 Noon on Wednesday
  • Total rainfall of 1-2 inches is expected across the local area with this event on average, and 2-3 inches of rain is possible possible in some spots
Discussion:
Scattered showers are possible during the daytime hours on Tuesday - and an isolated thunderstorm cannot be completely ruled out on Tuesday.

The most likely time period for more numerous showers and thunderstorms is still expected to be during the pre-dawn and morning hours on Wednesday, mainly from 5am to about 12 Noon on Wednesday.

Locally heavy downpours of rain are possible during periods of thunderstorms, especially from 5am to 12 Noon on Wednesday.

Total rainfall of 1-2 inches is expected across the local area with this event on average, and 2-3 inches of rain is possible possible in some spots, especially if more than one round of thunderstorm activity is observed at a given location. Again, this would be more likely to occur from 5am to 12 Noon on Wednesday, based on present indications.

At this time this event does not appear likely to produce widespread and/or organized flooding across the local area, but a few of the more flood prone low lying areas (i.e., some of the more vulnerable low water crossings and the like) may need to be monitored at times, especially during any persistent periods of locally heavy downpours that may occur in some parts of the area. With the more numerous shower and thunderstorm activity currently expected to occur between 5am and 12 Noon on Wednesday, this would be the most likely time period where any potential concerns could possibly arise.


We will continue monitoring the situation and issue updates as conditions warrant.

Forecaster Confidence (Low/Moderate/High):

Moderate to High
