Tuesday, August 27 forecast: Summer swelter’s days are numbered

Summer’s swagger is back. We’ve had 3 days in a row now with highs in the mid-90s. The stretch isn’t over, but this late burst of summer heat won’t last into September.

A bigger dip in the jet stream is already moving into the Pacific Northwest. And, with a bigger dip in the jet we’ll get a stronger push of mild air. Before this happens, we’ve still got a couple of more days in the furnace. Temperatures Wednesday and Thursday shouldn’t have any problem climbing back into the low to mid-90s with heat indices approaching 100°.

Rain chances through Thursday aren’t zero, but most area will remain dry. Look for isolated showers and thunderstorms to bubble up mainly during the late afternoon and early evening.

Rain chances will perk up Friday as a trough amplifies across the East. The first of a pair of cold fronts will drop into the area. Scattered showers and thunderstorms will dampen the end of the week with rain chances highest Friday afternoon through early evening. No severe weather is expected, but pockets of heavy rain and lightning are likely.

For those heading out to Friday night football games, be ready for rain and possibly some delays. The shower and thunderstorm activity should fade quickly as we push past sunset. Temperatures will be cooler, but it will likely feel pretty humid.

Drier air will push in from the north over the weekend with the second of the pair of cold fronts arriving Sunday. Showers and thunderstorms will remain possible Saturday, mainly along and south of Hwy. 60. The risk for rain will shift even further south Sunday, mainly south of the state line. Labor Day looks partly sunny and dry.

We may have some rain to contend with as we go back to work next Tuesday, but temperatures look very mild. The milder mode likely sticks around throughout next week with no sign of another major summer surge in the long-range pattern.
