Storms Threat/Future Radar

Storms Threat/Future Radar

Today will be hot much but it is hands down the hottest day in the forecast for the next week.

Without any thunderstorms to stop the temperature climb, today should top out in the middle nineties.  Anything above 94° would make this the hottest day of the summer. We hit 94° three times last month.

A Heat Advisory is in effect all afternoon and into the early evening. Look for the Heat Index to rise into the 103-108° range later today.

Storm Review: Damaging wind north of Springfield Saturday morning

A cool front is on the way!  This features will knock our temperature and humidity way down for most all of next week.

More showers and thunderstorms will lead the charge with this front late tonight.  I expect storms to fire to our north and slip south into the Ozarks by late evening and into the overnight hours.  The storms which first start up may produce gusty winds and small hail north of Springfield affecting areas around Lake of the Ozarks, Hermitage and Stockton this evening.

The cooler conditions start on Monday with the high temperature stopping around ninety.  But the real cooler and drier air will kick in Tuesday and last through the rest of the week.  Lows may drop into the lower sixties by Thursday morning while high temperatures stay in the eighties through Friday.

8-8-2015 8-26-40 AMThis weekend will be a sizzle in the Ozarks with highs well into the nineties.

This morning, a band of storms has done well surviving from Kansas into western Missouri.  These storms will move deeper into Missouri and may contain some hail and gusty winds in areas northwest of Springfield.

Otherwise, the region will be hot both today and Sunday.  Highs will reach into the lower nineties today and middle nineties on Sunday.

The Heat Index (HI) will top 100° easily on both weekend days and may briefly rise over 105° during the late afternoon and early evening on Sunday.

A Heat Advisory is in effect for the Ozarks both today and Sunday.

A cool front will arrive on Monday with a few thunderstorms. This front will being out daily highs back down into the eighties to start next week.

What is the Heat Index?

The heat index is a convenient way of expressing how hot we really feel when humidity is factored in.

heatindexchartBy using the familiar temperature scale, the heat index gives us a “feels-like” temperature which is more realistic when gauging how our body will feel due to the combination of heat and humidity.

Humidity matters because our body’s natural cooling process involves the evaporation of perspiration from our skin.  High humidity slows the evaporation down which might lead to warmer body temperatures.

The heat index is calculated by knowing the temperature and the relative humidity.  The chart above can then be used to arrive at a heat index value.

When using relative humidity, keep in mind that morning relative humidity is usually a lot higher then during the afternoon.  Using a forecast high temperature and morning humidity will lead to some very large (and wrong) heat index values!  Always use the current temperature and humidity when using the chart.

Our latest run of hot temperatures will reach its hottest point today before readings start heading back down later this week.

Today will be as hot as yesterday across the Ozarks.  I see most areas reaching into the middle nineties.  On Monday, Springfield reached 94°.

Of course, it’s the humidity which is making things worse.  The combination of heat and humidity will cause Heat Index (HI) values to reach to 100-105° today commonly.  A few areas will see the HI climb close to 110° by late afternoon.

An excessive heat warning was issued by the National Weather Service for all of southwest Missouri today.

A cool front will start to change things on Wednesday.  This front will shave temperatures back a tad starting on Wednesday and will also spark a few showers or thunderstorms in the Ozarks. Overall, the threat of rain is not very high in connection with this front.

After the front passes, temperatures will be cooler for the rest of the week with highs staying in the upper eighties and lows finally dropping below seventy.

Excessive Heat Today

Even lovers of summer heat may not care much for the weather to start off this work week!

Today and tomorrow will be hot days.  I’m looking for the thermometer to peak in the middle nineties both days in Springfield.  Humidity is what is pushing the heat to the levels of caution.  Dew points are running in the middle seventies which is on the high end of summertime readings.

The heat index will run between 100 and 105 degrees today with some areas west and northwest of Springfield heading as high as 105 to 108 degrees during the peak of heating this afternoon and early evening.

A cool front will trim these readings back by the middle of the week. This front also has a small shower and thunderstorm potential attached to it late Wednesday.

High temperatures will drop down to the eighties on Thursday and Friday, just in time for the opening of the Ozark Empire Fair!

Hot Weather Returns

A heat advisory kicks in for Springfield and much of the area west and north of town today.

Joplin and areas roughly along I-49 and points west are under a heat warning.

The shower chances are gone now as a dome of warm air in the upper atmosphere build into the area.

This will mean a run of high temperatures back into the 90’s starts today and will run through nearly all of next week.

The humidity is running on the high side too and this combined with  hot temperatures will send the heat index values into the 100-108° range during the afternoon and early evening hours today. This will probably be repeated for the next several days.
