Warm and Muggy for the Week. Chance of Thunderstorms Daily

It seems as though Spring decided to leave us and allow Summer to move in.  Temperatures yesterday were just awful, nearing 90 and above in spots with poor air quality.  Hazy, hot, and humid (or the Triple H as I like to call it) will be the words for the week with each day featuring a chance of afternoon/evening thunderstorms; you're typical summer-like pattern.  Best chance looks to be late in the week around Thursday-Friday time frame, but even then the highest percentage is around 50%, so it's a deal or no deal kind of situation.  Any storms that develop today will definitely have the chance to become severe with strong winds, large hail, frequent CG lightning and an isolated tornado or two.  Already had reports of 3.25" hail in the Wilkesboro area in NC, so that's an example of what to look out for.  Stay safe and have a good day.

Rainy/Cooler Period for the First Half of the Week. Dry/Warm Second Half....

From radar and WV imagery this morning, our upper level system will swing through the Southeast today producing showers and some storms as they increase in coverage.  A few of these storms could get strong or severe in spots depending on who sees extended breaks in the clouds, which will aid in creating some instability.  Considering the lowering of the freezing level aloft, storms will have potential of producing hail under those that are stronger.  I will not be surprised if some folks stay in the low 60s for highs tomorrow in the cooler areas given the cold core that will be present with this system.  The ULL will stay in place for a few days before finally departing later this week, allowing us to dry out and warm back up into the 80s for highs.  I don't foresee any major severe weather threat this week so we should stay clear of that compared to previous weeks where there seemed to be a constant threat for such.

Have a good day.

Warm and Dry Today. Possible Active Tuesday

It's been a fantastic few days with plenty of warmth and nice weather after experiencing those colds low temperatures during late last week.  We should keep this up for throughout today though a few isolated storms is possible in spots.  80s to around 90 should be the high temperatures across the Southeast. 

As for what will be in store for tomorrow, the next system is expected to make a trip into the Southeast region during the day Tuesday.  A system in the Dakotas will depart from there and head through the OV into the eastern areas of the Southeast during the afternoon/evening hours.  A boundary will drape itself along the Savannah River Valley with plenty of instability, moisture, and decent shear aloft.  This could cause some strong to severe storms to fire off during the peak heating hours with a few isolated supercells in the more favorable areas.  I will make note that it is not the possible tornadic development to be most concerned with, but rather the gusty winds and damaging hail will be our main threats with any of these storms.  Initiation of convection also appears to be earlier than expected, starting across the NC mountains during the early part of the afternoon and spreading southeastward across the Carolinas and parts of GA.  Stay alert if your area happens to be underneath one of these storms throughout the day.  This activity should taper off Tuesday night and re-appear on Wednesday, though it will be less threatening since the ridge to our west will move closer and thus cause the dynamics present today to gradually weaken for tomorrow.
