Discussion

A cool, rainy day is an increasing possibility at the end of the week…a cool frontal system is stalling out just south of here and a wave of low pressure will ride along its boundary zone later in the week. Temperatures will trend downward over the next few days and be closer to the 80 degree mark for highs by Friday rather than the 90 degrees that we’ve been accustomed to in recent days. Showers are likely in the cooler air mass late this week and there is a growing chance for some steady rain as we close out the work week and begin the weekend.
