First Alert Day on Wednesday.

RALEIGH, N.C. (WTVD) -- First Alert Day - Wednesday 2am - 9am: Isolated strong to severe thunderstorms will be possible Wednesday morning. Damaging straight line winds, and large hail will be the primary hazards, but a brief tornado is also possible.

Good morning! High clouds have begun streaming into the area this morning, and these will stick around through the day. Outside of a stray shower, high pressure will help to keep conditions dry through the day. Morning temps are in the upper 50s to low 60s.

Thunderstorms will develop overnight and through morning commute time Wednesday. The front will pass later in the day Wednesday. In terms of severe, we still can't fully rule out gusty winds, hail and even an isolated tornado, but with storms expected to come so late tonight into early tomorrow morning, chances aren't high, and best changes will likely be east of the Triangle. Locally heavy rain will be possible. Most totals will be around 0.25" or less, with isolated higher amounts.

By tomorrow afternoon, another surface low looks to begin to develop just off the coast as the first low over the Great Lakes begins to occlude, which could bring another quick round of thunderstorms to the area. However, this low looks to quickly move off to the northeast, drying us out tomorrow night.
Humidity will drop Thursday with highs in the upper 70s to low 80s. Lows will be in the mid/upper 50s.

Pleasant conditions will linger through the holiday weekend, as winds stay generally out of the northwest. Historical averages for this time of year are around 80, so we'll be well below average this weekend with highs in the mid/upper 70s and lows in the 50s.

Shower chances could increase again late this weekend as a weak disturbance tracks over the Southeast. The rain chance will be at 20%, so expect generally dry weather.

Have a great day!
