Warmer again Monday and Tuesday; Then sharply cooler

A cold front swept across Minnesota early on Sunday and treated us to nearly-seasonable temperatures in the 60s and 70s. Scattered light afternoon rain showers have popped across southern Minnesota. Rainfall amounts will be rather minimal.

Warmer Monday and Tuesday, then cooler again

Monday and Tuesday will see a quick warmup. The Twin Cities should get a high near 80 on Monday and maybe 85 on Tuesday.

Another cold front will usher in cooler Canadian air for a few days beginning on Wednesday. The Twin Cities’ high is likely to be in the upper 60s that day.

On Thursday we will celebrate the autumnal equinox (at 8:04 p.m. if you are a stickler for precision) with highs from the mid 50s to low 60s.

Rain. We want rain.

How busy has your rain gauge been this month? Mine has measured a paltry 0.18 inches so far in September. Watering continues as rain is badly needed, especially in many parts of central and southern Minnesota.

Forecast models are fuzzy on when we might get some decent rain. Scattered showers might dampen parts of the state Tuesday night into Wednesday, but that system looks to be weak.

A better chance for widespread rain might come our way around Friday-Friday night.

Hurricane Fiona

Speaking of rain, Hurricane Fiona has been lashing Puerto Rico with heavy rain and is headed into the Dominican Republic. It is likely to strengthen as it turns north, becomes a major hurricane (“M” on the map) and then tracks northeast toward Bermuda.
