Winter Weather Advisory

Monday, August 27, 2012

Extreame heat ahead-Heat wave in full swing in by midweek this week. Highs near or topping 100.F by Thursday likely breaking record values. Drought condtions likely to expand with no rain in sight through next weekend.

Regional weather view.

This is not something too typically talked about nearing September but a significant heat wave will be moving into the region from the west bringing extreme heat ranging from 95 to 105.F to Nebraska, Iowa, Missouri, Minnwesota and parts of Western Wisconsin. Because of the way the center of the high pressure is located the most intense heat will stay in a more westerly direction instead of extending all the way across the map. There is really no rain is sight for most of the area because of this area of hot high pressure blocking weather system from coming into the region. In fact drought will really be expanding this week across the map.

Local and Metro views.

Extreme heat expected by Wednesday-Friday

The big story and the only story taking place in the local area this week is extreme heat expected to develop slowly in the coming days. In fact record breaking highs are likely with this heat wave. Were expecting a long strong of sunny hot dry days starting Tuesday and continuing through Saturday. There is no rain forecasted at this time which will expand drought conditions across the area. Tuesday will be the start of the big warm up. Highs will heat up to around 90.F across the region. Lows will fall into the middle 60s. The heat really kicks up starting Wednesday, Thursday and Friday will all be very similar in conditions. Strong southerly breezes and a strong hot August Sunshine will allow highs to heat up and range from the middle 90s to lower 100s Wednesday through Friday. Thursday will be the hottest day in which we will break record high values with widespread highs in the upper 90s with lower 100s possible especially in places like Urban Rochester and hot areas like Winona, Red Wing and Austin. This heat wave will be different from past heat waves we had this summer. This time the heat will be more of a dry air nature, meaning dewpoints will be rather low, which may actually help to increase the temperature, but decrease the heat index values, and there wont be much of a sticky feeling in the air as in past heat waves. Still it should be taken seriously because it will be long lasting and very hot. Temperatures will start to cool off with a cool front on Sunday, unfortunately it looks to come through dry at this time.

Tuesday, Sunny and Hot! Highs in the low to mid 90s. Tuesday Night, Clear skies lows in the mid  60s to upper 60s Urban Rochester.

Looking Ahead

Early Monday is the next chance of rain for the local area and it looks slim at this time. Starting off into the middle of next week the models show a hint and possible some widespread decent rains, a storm system moving across Iowa could develop and bring rains to the local area, behind this, much cooler and dry conditions take hold for the weekend for the weekend of the 8th. The models then keep it dry with more seasonable temps through the 11th before a slightly warmer pattern beings to press eastward from the west.
