Meteorologist Myles Henderson’s First Warning Forecast

Cool again today but warmer ahead… Expect highs in the low to mid 80s today, just below normal for this time of year. Dew point values will remain in the low 60s and upper 50s. We will see plenty of sunshine this morning with clouds building near the coast this afternoon. A stray shower is possible but overall rain chances remain very slim.

Heat and humidity return by the end of the work week. Highs will climb back into the mid 80s on Thursday and to near 90 on Friday. As temperatures go up, so will the dew points, making it feel very muggy again. Heat index values will return to near 100 by Friday afternoon. Expect more sunshine and low rain chances through the end of the week.

Today: Mostly Sunny to Partly Cloudy. Highs in the low to mid 80s. Winds: NE/E 5-10

Tonight: A Few Clouds. Lows in the upper 60s. Winds: SE/S 5-10

Tomorrow: Mostly Sunny, Warmer. Highs in the mid 80s. Winds: S 5-10
