PREV DISCUSSION...(ISSUED 325 PM CDT MON JUL 18 2016
SHORT TERM...Tonight Through Wednesday
Tuesday will be much like today with a slightly better chance of
diurnally driven showers popping up throughout the afternoon.
Southern Arkansas will see slightly better chances. A ridge of high
pressure will eventually slide east through the week with lesser
rain chances as we get beyond Tuesday. Heat will be the main
headline with temperatures bumping up a degree or two each day. A
few areas may not reach or sustain criteria on account of an
afternoon pop shower. However...with the warming trend in place went
ahead and expanded the heat advisory to Wednesday. May even be
approaching heat warning criteria in eastern Arkansas by mid week.
It`s important to mention isolated cells may produce locally
damaging downburst winds with brief heavy downpours over the next 2
afternoons. These storms will be brief with little to no movement.
LONG TERM...Wednesday Night Through Monday
5h ridging continues for the remainder of the week squashing or
severely minimizing the chance for any rain through at least
Saturday. As we get into Sunday and early next week the ridge either
weakens a bit or transitions well to the west of the area allowing
for NW flow, weak troughing and falling heights. Either way, it
seems plausible that a slight chance of showers or storms will
return by then.
Temps will continue to run above normal with max HI`s ranging at or
above 105 through Sat. If todays 12z run of the ECMWF is correct,
then temps may return to near normal by early next week. This run
even hints at a cold front moving into the state Mon night. Time
Heat Advisory until 9 PM CDT Wednesday FOR Arkansas-Baxter-
