Heat and Humidity Possibly Returning Next Week

The jet stream pattern is changing once again next week with another ridge of high pressure developing over the center of the country.  This would place the strongest winds within the jet stream very close to the Stateline beginning next Tuesday.

Low pressure will develop over the central Plains early next week.  This will allow a warm front to develop and lift closer to the Stateline beginning Monday night.  Following the front will be a very hot and humid air mass.  If the front stalls near northern Illinois and southern Wisconsin, showers and thunderstorms will be likely holding temperatures down Wednesday and Thursday.  The threat for heavy rainfall would also be high due to the amount of increasing moisture in the atmosphere.  If, however, the front slips further north highs will easily warm into the low 90's beginning Wednesday.  It doesn't look like the heat would last as a little cool down arrives late in the week and for next weekend.
