What to Expect Today: Scattered to numerous showers/storms again today. A few isolated showers developing this morning, but becoming more widespread this afternoon/evening before diminishing tonight. Won’t be an all-day, constant washout, but expect passing showers at times, with some periods of heavy rain. Localized flooding is the main concern with storms today.
Rounds of showers and storms will move through the area each of the next 5 days. Temperatures will be between the 70s in the morning and 80s in the afternoon with high humidity.
Key Messages: Confidence is high that we’ll be in a wetter-than normal, summertime pattern this upcoming weekend, with high chances (70-90% chance) of primarily afternoon/evening showers & storms each day. NOT anticipating all-day washouts each day, with dry and wet periods expected. Mainly dry nights and early morning hours. No excessive heat concerns with highs generally in the mid 80’s each day. Keep this in mind if you have outdoor plans! Have a backup plan, and a place to go (safely indoors) in case you hear lightning and if traveling, watch for flooded roadways!
