As the Sun rises at 6:08 AM CDT and sets at 8:32 PM CDT the length of available sunlight reaches its maximum amount, at this latitude, of 14h 24m over the next few days. Tomorrow is the Summer Solstice in the Northern Hemisphere, the longest day of the year.

The weather forecast for my area looks much the same for the next 7 days: hot and dry with soaring highs in the mid to upper 90's and coolest in the low to mid 70's at or around sunrise. There have been no excessive or otherwise heat advisories for McCurtain County issued yet. A heat advisory is issued when the heat index is expected to exceed 105° F (100° F in New York City) or if nighttime lows are expected to be greater than 80° F for two or more nights. The Shreveport NWS does not use mesonet.org for its data. It uses the local airport with automated updates every 20 minutes and not a reliable source for this area to use for higher temperatures and heat indices(lately). The graph below is from mesonet.org.

From their website:

The Oklahoma Mesonet is a world-class network of environmental monitoring stations. The network was designed and implemented by scientists at the University of Oklahoma (OU) and at Oklahoma State University (OSU).
The Oklahoma Mesonet consists of over 110 automated stations covering Oklahoma. There is at least one Mesonet station in each of Oklahoma's 77 counties.
At each site, the environment is measured by a set of instruments located on or near a 10-meter-tall tower. The measurements are packaged into "observations" every 5 minutes, then the observations are transmitted to a central facility every 5 minutes, 24 hours per day year-round.

In the past 6 days since the last entry it has been hot and dry with temps in the mid 90's and overnight lows in the mid 70's. Not much else to report other than heat indices 100 to 105. This weather pattern should remain the same until next week some time, if there are storms.

Using the approximate temperature (red) & dewpoint (green) lines on the graph above you can estimate the Heat Index on the chart below.

The Heat Index reached 106° with a Temp of 95° at 4:30 PM (mesonet.org)

Sunday June 13 Heat index comes close to 105° F.

4:30PM Temp 94° F. | 34.4° C. Heat Index 104.9° F. | 40.5° C. (mesonet.org)

As the sun set last night June 10 (8:30) loud thunder started. The lightning was very close and lit up the sky. Many thunderstorms passed overhead, one after the other for 3 hours, although some sources show heavy rain after midnite. I believe these storms were small and moving in different directions over different locations, but one thing is certain: at least 0.8 inches of rain fell(mesonet.org)! The frequency of cloud to ground lightning and low cloud ceilings made for a frightening event. I was gun shy and shivering until the brilliant flashes and accompanying booms of thunder finally stopped!

June 10 Radar Animation 12 AM until midnight will show the many storms here.
