Meteorologist Myles Henderson’s First Warning Forecast

A very summer-like week… Highs will climb into the upper 80s this afternoon, a few degrees above normal. With the humidity, afternoon heat index values will reach the mid to upper 90s. Expect mostly sunny to partly cloudy skies this morning. Clouds will build by midday with scattered showers and storms popping up this afternoon. A heavy downpour or thunderstorm is possible but severe weather is not expected.

Rain chances will fizzle out this evening and we will see partly cloudy skies tonight. Lows will return to the mid 70s overnight.

Highs will warm into the low 90s tomorrow and Wednesday. Afternoon heat index values will climb to near 100. We will see sunshine in the morning with clouds building by midday. Showers and storms will pop up again each afternoon.

Highs will drop into the upper 80s for the end of the week. It will still be humid with heat index values in the 90s. We will continue to see a mix of sun and clouds with afternoon showers/storms possible. Highs will slip into the mid 80s, closer to normal, this weekend.

Tropical Update

We are watching a non-tropical, surface low pressure system centered about 1200 miles southwest of the Azores. Environmental conditions are expected to be only marginally conducive for the low to acquire subtropical or tropical characteristics while it moves little over the next day or so. By Monday afternoon, the low is expected to move toward the north or NNE and continue that motion through Tuesday.

* Formation chance through 48 hours: Low (20%).

* Formation chance through 5 days: Low (20%).
