AREA FORECAST DISCUSSION National Weather Service New Orleans LA 412 AM CDT Mon Jul 6 2020

DISCUSSION. Starting off the discussion, yesterday's PW measured by our upper air sounding was 2 15". BOTH flights. Needless to say, it was a wet day. No pattern change today and model soundings actually show a slightly bump in PW's, so expecting a near repeat. In fact, the latest HRRR run shows storms developing south and west of I-10 corridor in the morning and progressing northeast during the afternoon. That's basically what happened yesterday. Looking at the radar qpf coverage before it was reset a few hours ago, a subjective 90% of the area saw measurable precip. Thus, will be sending out the forecast today with around 90% POPs.

Main concern for today is heavy rain and flash flooding. Scrolling through radar imagery from yesterday, some very impressively high numbers were seen. Instaneous rainfall rates of over 8" per hour occurred a few times. That's 1 inch of rain in 7-8 minutes. While it's quite rare for a rate that high could be maintained for very long, multiple places did see 4" over an entire hour yesterday. In addition, it's not too unlikely that a pattern like this can produce upwards of 5 to 6 inches over an hour. Location is everything though and where the training of these intense storms occur will determine if flash flooding develops.

The upper level pattern doesn't appear to change going into Tuesday. CWA continues to sit in a region of weakness between 2 ridges with ample moisture in place. Therefore, the same POPs and threats can be expected to continue.

The pattern will finally starting to gradually change Wednesday onward. The ridge centered near the 4 Corners region of the country will begin to deepen and expand eastward. This will increase subsidence and bring in drier air into the column. Rain chances will slowly decrease as this transition takes place with POPs possibly as low as 20 to 30 percent on Friday. Of course, lower POPs with increasing 500mb heights means high temps will likely begin to soar. Could be looking at heat advisories returning this weekend.

MEFFER

AVIATION. All sites will eventually have IFR or even LIFR conditions with TSRA producing low vis and cigs. Outside sh/ts VFR will be noted at each terminal. A lull in activity once again overnight only to give way to more of these same conditions for Tue.

MARINE. A general weakness associated with a sfc trough near the coast and a sfc high over the SE gulf will keep winds mainly out of a westerly direction through much of the week. Some flux to an onshore flow may be produced temporarily through the week and Nocturnal sh/ts will continue each night through atleast mid week. Higher winds and seas will be found in and around sh/ts. Relatively drier conditions look to be on the horizon for Thu and Fri. The exception could be waters east of the Miss River. But sh/ts look to be back again by the weekend for most waters.
