I’m on vacation the next couple of weeks but I want to get the word out about a few weather hazards we’ll be looking at this week in the Valley.
As most already know, today and Tuesday will bring us some hot and humid weather conditions. The combination of hot temperatures in the 90° range and tropical dew points will push heat index values into the 95 to 99 degree range.
Nighttime lows will not cool off much more than the low-70s and those dew points will stay elevated as well. Expect some warm and muggy nights.
With all of this heat and a humid air mass the atmosphere will be fairly unstable during the peak heating hours in the afternoon and early evening. It wouldn’t take much for spotty thunderstorm to develop just about anywhere. Any passing storm during the afternoon or evening hours is likely to be non-severe.
Relief from the hot temperatures and high humidity will arrive on Wednesday with a cold front. The front will also bring a Marginal Risk (Level 1 on a scale of 1-5) of a strong to severe thunderstorm. High winds will be possible in the stronger thunderstorms.
Showers and thunderstorms will likely continue Thursday and Friday but temperatures locally will back off to the upper-70s to low-80s. Periods of heavy rainfall will be possible during the latter part of the work week.
So far the Independence Day weekend looks mainly dry. There will be showers and possible thunderstorms around so rain in any one location can’t be completely ruled out. Temperatures are looking to be in the upper-70s for daytime highs and it will not be nearly as humid.
I’ll keep you updated on any severe weather that might develop on Wednesday. Until then, be safe out there.
