FORECAST IN DETAIL
It’s been a few years since we’ve stared down a lengthy stretch of very high temperatures like this, so prepare to take it slowly and spend plenty of time in cool places. Pretty much any of the next three days could reach 100 across at least parts of the area. It’s possible that similar readings will continue even further into the week. Water. Sunscreen. Hat. That’s if you venture out, which you should really limit during the mid-morning through afternoon if possible.
Today (Saturday): Nasty. If you have anything to get done outdoors, you should plan on doing it very early or quite late. Otherwise, take it easy! The air is bad and it’s ridiculously hot. Air conditioning will be in high demand as mostly sunny skies allow the strong July sun to punish those of us on the ground. It’s one of those days where it might be mid-90s by or just after lunch. That sets the stage for a run at 100, at least in spots. Overall, upper 90s to around 100 should be common. Heat indices are likely to peak in heat advisory range of 105, or a little higher. There may be an isolated late-day into evening storm, but don’t bet on it. Confidence: Medium-High
Tonight: Any small risk of a thunderstorms diminishes with time, given the loss of daytime heating. It’s pretty uncomfortable through sunset at least, with heat indices staying near 100 until dark, especially in the city. Once the sun is down, the slow dip through the 80s is underway. Overnight lows eventually reach the 70s most spots. A range from about 72 in the coolest rural areas to perhaps 80 downtown. A touch or two of fog is possible by morning thanks to light winds and high humidity. Confidence: Medium-High
Tomorrow (Sunday): For all real purposes, this is a repeat of Saturday. If we try to over-science it, there could be a little lower dew points although they remain high and it remains sticky. If we’re lucky maybe a degree or so less heat as well. I wouldn’t necessarily bet on either since these things are dependent on a bit of a wind shift more than anything. And this air mass is pretty stagnant either way. Highs again are largely in the upper 90s to near 100. We again run the risk of a late-day storm or two. Confidence: Medium-High
Tomorrow night: Another less than perfect summer evening, as sweaty conditions persist. Like this evening, it’s a wait until about sunset to really feel more comfortable outdoors, although evening activities will certainly be possible. Overnight lows are mostly in the mid-70s to near 80. Confidence: Medium-High
A LOOK AHEAD
More of the same on Monday. The question may be how many clouds. Otherwise, this actually has hints it could be the hottest of the stretch. We’re at least doing mid-90s to around 100, and if we have mostly sunny skies, it could largely be near or above 100. With dew points near and above 70, we’ll likely be crying uncle by this point. We’ll have to eye areas to the northwest for some late-day storm potential as a front nears the broader region. Confidence: Medium
Tuesday is either another very hot day or just a normal hot day. Some modeling keeps us in the low-to-mid 90s thanks to extra clouds, but the better modeling tends to keep us in that mid-90s to 100 zone once again. The heat wave rolls on however we slice that one. The ever-present threat of a late-day storm is there too, perhaps higher than recent days with a front potentially nearby. Confidence: Medium
