Update: 5:16 p.m.
From Storm Team 4’s Brian Gotter:
“Cristobal has arrived with scattered showers and downpours, humidity and gusty easterly winds to 45 mph this evening. There is a wind advisory for all of SE Wisconsin until midnight for those high gusts, and the rain should be out of here around midnight as well.
Since the storm system is moving so quickly, the rain totals will be held to around a half inch with a few higher amounts. Lows tonight will remain in the upper 60s with the high humidity.
We stay rain-free in the morning hours until the early afternoon, then showers redevelop for the late afternoon and evening with an addition 0.25″ to 0.50″ of rain. There is no severe weather threat for tomorrow. Before the rain, the high temp will get into the upper 70s.”
Storms such as what meteorologists expect today in Southeastern Wisconsin aren’t uncommon. The source of them – a former tropical storm – is very uncommon around here.
“Here comes Tropical Depression Cristobal!” says Storm Team 4 Meteorologist Brian Niznansky.
“From a science stand point, this is a historic track for Cristobal, but we’ve certainly seen much bigger storms before across the Great Lakes.”
He says weather will remain quiet and mild from the morning through the early afternoon, but wind speeds will rise as the rain and storms enter the Milwaukee area.
“The rain should arrive around 5 p.m. in Milwaukee. The rain may be heavy at times and there is a very small chance of a severe thunderstorm or even a brief spin-up tornado. The general east wind will gust over 30 mph,” Niznansky says.
“Showers and storms probably continue up until midnight, then the rest of the night should be dry. Up to an inch of total rain is likely. More showers and storms are possible on the backside of Cristobal and cold front tomorrow afternoon, with an additional 0.25″ of rain is possible.”
