WIND SHIFT LATE

A "fropa" is coming soon!  That's short for a frontal passage, to occur in Indianapolis from 10 pm top 12 am.  This front will signal a change to start the weekend.  Humidity levels will drop and more comfortable air will arrive.  You wil will really notice the change Friday afternoon and really enjoy it come Saturday morning.

Dew point levels in the 70s the past several days retreat to the low to mid 60s.  We will not remove the humidity all together but will feel more comfortable.

WEEKEND OUTLOOK

It's shaping up to be another fine July weekend.   Sunshine will be plentiful along with a few clouds Saturday and again Sunday.  We will start warming again Sunday and humidity will creep up late in the day.  The returning humidity could bring along a late shower or thunderstorm especially over the northern third of the state.

HEAT WAVE

A real summer sizzle is still in the works and set to unfold here later next week.  Long range forecasts continue to produce a massive upper level high pressure - dome of heat over the central US.  Under the high pressure, sinking air compresses and heats and suppresses cloud build, meaning no rain.

The 8 to 14 day forecast from the Climate Prediction Center has a high probability of above normal temperatures for much of the nation.  The question really, is how high?  The projected strength of this hot dome may send temperatures well above 100° and break heat records in the central U.S.

A sting of 90s are possible here starting middle of next week.  There is  a wildcard, the location or center of the high.  A slight westward anchored high pressure could allow a few fronts to slide in from the north east.  That isn't the conventional thinking right now, ensemble computer projections suggest that there could be as many as eight consecutive days of 90° heat!  Stay tuned we are monitoring this carefully.
