June 28th-July 3rd: Historic heat wave/drought

July 1st Updated:

Some scattered showers and thunderstorms will be possible Sunday afternoon into Monday afternoon - right now I suspect they will be widely scattered in nature - perhaps isolated is a better word.  A few boundaries and impulses will move through the region over the next 24-48 hours.  It is likely that these will produce at least a small chance for some storms.

The most intense storms could produce nickel to golf ball size hail and high winds - lot of lightning, as well.  Pockets of 1-3" of rain will be possible if you find yourself under a heavy storm - again these will be scattered in nature - especially over part of southeast MO into southern IL and NW KY on Sunday afternoon.

Temperatures over the next 1-3 days will be somewhat impacted by cloud cover.  Depending on the amount of clouds there could be a reduction in temperatures by 2-4 degrees.

It still appears that temperatures will be 100-105 across the region on Sunday afternoon and in the 98-102 range on Monday and Tuesday.  

Another intensification of the heat wave is possible Thursday into this coming weekend - something I will be keeping an eye on.  Either way the hot weather is here to stay for awhile.

Intense heat and drought over the region.  Hot temperatures will be cause for concern on Thursday into the weekend - would not be surprised to see record or near record high temperatures above 100 degrees in many counties.  Use caution.

Some isolated severe storms possible on Sunday afternoon in the area - hail and gusty winds - lightning and heavy downpours in the most intense storms.


I am posting information about the drought on the weather Facebook page - click here and hit like at the top of the page.
.




Basic heat precautions.  Use care in the coming days - check on elderly residents.   

Hottest part of the day will likely be from 1 pm through 6 pm.  The 11 am through 7 pm will be very warm to hot - but the most intense heat is typically 1 pm through 6 pm. 

Monitor radars for any storms that pop up



No wild card in this update - historic drought will continue this week.

HEADLINES:  A record or near record heat wave is developing over our region - many areas will experience record or near record temperatures over the coming days.  The duration of this event could also break some records.



Many areas will be above 100 degrees on Thursday - Friday - Saturday - Sunday - Monday - Tuesday.  We are in a 1930s and 1950s weather pattern - you have heard me say that for the last decade - that continues and this drought is just further evidence of that fact.

Here are a few statistics from Paducah, KY
 

We are looking at breaking some decent records. If we reach 101 degrees for four or more days in a row then you have to go back to the 1930s, 1950s, and 1988 to have experienced heat to that degree.

The hottest day in June (according to official records for Paducah) would be 106 degrees - set on June 26, 1942.

The hottest day ever recorded is 108 degrees set on July 17th 1942 (we tied that on Friday the 29th of June 2012)

Here is what I have dug up on Paducah, Kentucky

Some other years
July 17, 1942 it was 108 degrees**
August 4, 1947 it was 106 degrees
June 28, 1952 it was 106 degrees
June 30, 1962 it was 106 degrees

** Denotes the all time record high for Paducah.

* denotes: Four days in a row of 101 degrees or higher. Rare in this region.

Here is some more unofficial information

Some new crunched numbers - to show you how common or uncommon a heat wave like this would be in our region - these are unofficial numbers - I went back into the 1800s for the Paducah and Paducah area. This is what I found. The criteria I used would be a temperature of 102 degrees or above for four days in a row (or more). The years that this happened would be 1896, 1901, 1918, 1925, 1930, 1931, 1934, 1936, 1941, 1947, 1952, 1988. In 1918, 1936, and 1952 it happened twice - the only years I could find where it happened twice. The highest number of consecutive days that I could find was in 1901 8 days in July. This type of event is most common in July and August. I could only find 2 years where it happened in June - that was 1931 and 1952. Both of which brought 4 consecutive days of 102 or above in the City of Paducah or Paducah area. Obviously the 1930s were extreme years. You also had the great floods of the 1930s on top of the great droughts of the 1930s. See a common theme? Cycles come and cycles go.

In addition to the high/extreme temperatures - we are also, of course, in the midst of a major drought. Some places are now 12-18+ inches below normal in precipitation. There are some spots that have not measured 5" of rain this year, so far. That is simply stunning. 


Extreme caution is urged if you have to be outdoors.  Low humidity levels may also cause sweat to evaporate much faster than it normally would.  This means you may not be aware of your hydration levels.


Hottest part of the day will likely be from 1 pm through 6 pm.  The 11 am through 7 pm will be very warm to hot - but the most intense heat is typically 1 pm through 6 pm. 



Drink plenty of water.

Severe drought conditions will continue to intensify over the coming days - little or no rain is in the forecast.  Communities are urged to consider asking their local residents to start cutting down on water usage - before it becomes a serious problem.  This is especially true of communities that depend on lakes and reservoirs for their water.  

Community residents are encouraged to check on elderly people - also remember not to leave anyone (young and old - and pets) in cars.  Temperatures inside of cars can quickly heat up to 120-190 degrees.

Here are some of the high temperature forecast maps for Thursday into next week - these are incredible temps for our region - especially for so many days in a row.  

Keep in mind that locally higher temperatures are possible in some areas - bottom line is that it will be hot - whether it is 98 degrees or 105 degrees.  

Heat index values will be near actual air temperatures (because of the low dew points).  There could be a bit higher dew point levels on Sunday or Monday.

The temperature maps below are GENERAL high temperatures - some areas could be a bit lower and some areas could be a big higher - keep that in mind. 

  








Some high temp records for the past week - over 1000 of them.


Here is some interesting information from the Arkansas Weather Blog

Anyway, what caused it (the extreme temperatures)?  It was the perfect combination of what I call the "Triple Ingredients To Top 100" plus one other very important factor which made it get out of hand.  I'll explain.  Normally in summer here are the 3 ingredients to hit 100....

1. Strong high pressure
2. Dry ground
3. Ample sunshine

We had all of that Thursday plus one other factor which caused temperatures to reach levels never seen before in June weather history for Little Rock and other locations.... DRY AIR!

The presence of dry air allows the temperature to cool rapidly and efficiently at night, but it heats rapidly during the day.  Usually during an Arkansas summer, we have thick and high humidity levels.  Water vapor is the number 1 greenhouse gas in our atmosphere.  High levels of humidity will prevent temperatures from varying too much compared to when dry air is in place.  Heat gets trapped by water vapor and it's not allowed to enter or escape as efficiently compared to the drier air.  I hope this makes sense.

However, when the humidity levels are high, it feels even hotter due to the inability for your body to cool itself.  Evaporating moisture off your body is more difficult because the air surrounding you is already full of moisture.  When dry air is in place, the evaporation rate is much higher and you will not sweat as much.  This can lead to evaporational cooling.  That's what we experienced Thursday.  Dewpoint values were in the 50s and with readings around 107, it felt like 105 degrees.  There was an actual cooling effect due to the dry air.

Over the next few days, the humidity levels will begin to increase some and this will take temperatures down very slowly, but it will feel hotter because of humidity levels will increase.

Remember that as a general policy, in the long range outlook, I try not to mention severe thunderstorms more than 72 hours in advance (unless the signal is so overwhelmingly convincing that it warrants a mention).  I will mention thunderstorm risks and I will give as many details as possible.  Also remember you can view the long range severe weather outlooks by visiting the Storm Prediction Center's web-site - click here

Now is a GREAT time to buy a NOAA All Hazards Weather Radio.  Better to have one before storms strike than to be without one during an event.  I recommend the Midland Model 300 NOAA All Hazards Weather Radio - that is what I use here at my house!
