NWS Jackson, MS wrote its last area forecast discussion before the first event at Jun 10, 5:37 AM CST, 3 hours 43 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Jackson MS 637 AM CDT Thu Jun 10 2021 .UPDATE... Updated for 12Z aviation discussion && .AVIATION... 12Z TAF discussion: While most sites are prevailing VFR, intermittent MVFR/IFR conditions with both low ceilings and low visibilities will continue to occur through the period due to increasing coverage of showers and thunderstorms. Near thunderstorms, high wind shear and microbursts will be possible. By tonight, some decrease in storm coverage is likely with mostly VFR conditions prevailing except near thunderstorms. && .DISCUSSION... Today and tonight: Showers and storms that developed overnight mostly north of I-20 will continue through today, posing a continued threat for flash flooding. These storms should become more widely scattered by afternoon and evening and the flash floood threat should diminish, though localized flooding will still be possible in areas that experience heavy thunderstorm downpours. Highs today may be held down a bit due to scattered showers and convective cloud debris. Look for temperatures this afternoon to rise into the upper 80s F to near 90 F for most, though the areas north of I-20 that experience longer duration rains may be held to the mid 80s F. Later tonight, we finally begin to dry out some with only lingering showers remaining. The upper trough that has been responsible for the exceptionally rainy weather the past week will have moved just east of us by late tonight and should result in sufficient upper confluence to somewhat reduce rain chances heading toward Friday. Lows will fall into the lower to middle 70s F. /86/ Friday through Wednesday: The generally slow-progressing upper-level trough and persistent upper-level low pressure system will continue to break down Friday into Saturday, with the overall flow pattern amplifying and a strengthening ridge of high pressure taking shape along the spine of the Rockies. Downstream from this ridge, southward moving shortwave troughs will ripple through the upper-level flow and reinforce the southward advancement of a more continental (rather than tropical) air mass into our region through the middle of next week. Friday will probably be the last of our days with the tropical-like rainfall in the region, and northeast Mississippi has the greatest chance for heavy rainfall to train along the west side of the departing low. Lingering humidity through Sunday, and the increasing influence of heating to our west will result in some potential for dangerous heat conditions to develop in our area, but there is enough uncertainty with rain chances still in the forecast that I don't have high confidence for areas of 105+ heat index yet. We will monitor this with future forecast updates though. Humidity and rain chances will be pushed south toward and along the Gulf Coast Monday through Wednesday, and POPs were nudged toward a drier and more confined area similar to the consensus of deterministic guidance. /NF/ && .PRELIMINARY POINT TEMPS/POPS...
