Tuesday will start out like much of the past week…mostly sunny, hot and humid. But by 2pm scattered storms will start developing and then move our way between 3 and 5pm. These storms will be capable of very heavy rain, gusty winds, and frequent lightning. After 7 to 8pm we quiet down again and return to this stubborn dry pattern for another 3 to 4 days before we start seeing afternoon/evening storm chances return.
We’ll have a pretty decent weekend on tap, with highs in the mid 80s Saturday and upper 80s Sunday, but lower humidity on both days. Skies will remain sunny with no real chance for rain until Tuesday of next week.
Short range models are hinting at a slight chance for some scattered late afternoon storms tomorrow (Wednesday), mostly west and south of Richmond, though one or two could reach RVA. Nothing severe but rain could be heavy at times. The rest of the week should remain dry with temperatures holding steady in the mid 80s to low 90s.
An approaching cold front (which will knock our temperatures back a bit for this weekend) will bring clouds our way and a few afternoon showers and storms to end the week. I’m not anticipating anything severe at this point. Showers could linger into the first half of the day Saturday. After that, dry weather resumes heading into the new week.
No weather worries today for your Fourth of July celebrations. It will be toasty again today but not quite as oppressive as the past two days, with highs topping out around 90. There is only a very slight (10%) chance of an isolated shower or storm this evening but I think just about everybody will be in the clear for fireworks into the overnight period.
We’ll see a better chance for afternoon storms by Friday with an approaching front.
A heat advisory is in effect from noon to 8pm on Monday for heat indices that will range from 105 to 108 for a large portion of central Virginia. I would not be surprised to also see an air quality alert issued again for Monday due to the combination of high temperatures and humidity and a stagnate air mass that will likely lead to moderate levels of ozone.
