NFWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 29, 8:37 PM CDT, 2 hours 6 minutes earlier.
Area forecast discussion, Mar 29, 8:37 PM CDT, 2 hours 6 minutes before
Area Forecast Discussion...UPDATED National Weather Service Jackson MS 837 PM CDT Wed Mar 29 2017 ...SIGNIFICANT SEVERE WEATHER POSSIBLE LATE TONIGHT INTO THURSDAY... .UPDATE... Updated for evening discussion. && .DISCUSSION... Evening update: Tornado watch #101 was issued a bit ago for mainly western zones until 3 AM CDT. Numerous thunderstorms initiating late this afternoon near the east TX/southwest LA border have gradually evolved into two separate areas of convection this evening; one area progressing northeast into the Arklamiss Delta and another area hugging more closely to the LA coast. Relatively broad forcing helping trigger these storms could set off more in the watch area through late evening and the combination of wind shear and instability is enough in the watch area to be concerned about tornadoes. 00Z JAN sounding revealed steep lapse rates, but plenty of dry air and capping above the surface to provide an impediment for potent storms to easily transition east past the I-55 corridor. Activity has developed eastward into the region a little faster than anticipated and our forecast and graphics have earlier been updated to reflect observations and thinking through the night. /BB/ Prior discussion below: Tonight through Thursday night: The next 24-30 hours are expected to be quite active across the region with multiple rounds of severe weather possible. The main culprit will be an upper trough currently over the Southern Plains swinging eastward into the mid MS River Valley through the day tomorrow. The associated surface low is currently situated over south Kansas and will track ENEward into the Ohio Valley through tomorrow, dragging a cold front across the region tomorrow. Two rounds of severe weather are expected with this system - one late tonight through early tomorrow morning and another from around midday tomorrow into the early evening. The initial round of storms, currently over the TX/LA border, is being kicked off by a spoke of PVA/upper height falls pivoting around the main upper low. Ahead of these storms across northeast Louisiana, a rather favorable environment is expected to exist later this evening, with deep layer shear of up to 50 kt, a 40-50 kt low level jet, mid level lapse rates around 7 C/km, 0-1 km SRH of up to 100 m2/s2, and sufficient surface based instability with SBCAPE of 500-1000 J/kg. Ongoing convection and available high- res guidance suggests decent potential for supercells evolving into more of a QLCS as they advance E/NE into the Delta later tonight. Given the favorable environment in the western portion of our forecast area, we have relatively high confidence in severe weather overnight, with some potential for some instances of sig severe (2"+ hail, a strong tornado) as well. Forecast 0-3 km shear vectors suggest the greatest damaging wind potential with any bowing segments moving in a more SW to NE direction during this time frame. This convection should lose steam by around daybreak as it begins to outrun the best low level forcing and as instability reaches it's nocturnal minimum. A bit of a lull is expected during the mid/late morning hours as remnant storms from overnight continue slowly eastward. This, along with any significant development of coastal convection, will present a potential limiting factor for redevelopment of storms later in the day tomorrow. Nevertheless, new convection is expected to initiate around midday somewhere between the MS River and the I-55 corridor as renewed upper forcing moves across the region and deep layer shear increases. It is possible these storms will not initiate until the boundary reaches the I-55 area, so the threat for additional severe weather west of this area (and especially back into AR/LA) is very questionable tomorrow. Farther south, instability may be increasingly limited by convection earlier in the day, so uncertainty increases south of the I-20 corridor. The storms that do develop with likely need some time to percolate before reaching severe thresholds as they move eastward, suggesting the greatest potential for severe storms in our CWA with this second round will be around the Golden Triangle area (with perhaps greater potential north and east of the area). Once again, relatively steep mid level lapse rates are forecast across much of the area, suggesting the potential for large hail. In addition, weak to moderate instability and a respectable low level jet portends the potential for damaging winds. The greatest low level helicity is forecast to pull out of the area by early in the afternoon, so the window for greater tornado potential may be somewhat limited with the second round of storms. To reiterate, there is considerable uncertainty surrounding the second round of storms, and there's a decent chance that some parts of our area may not be impacted. However, it is worthwhile for everyone to keep checking the latest forecasts, because there is the potential for a significant severe weather threat where storms do develop. Storms are expected to exit the area by mid evening, with rain mostly out of the forecast area by midnight. Somewhat cooler air will filter in overnight. /DL/ Friday through next Wednesday: As Thursday's system pushes off to the east, quiet weather will prevail as surface high pressure builds over the region on Friday and Saturday. High temps will return into the 80s while lows increase again into the 60s. During the weekend timeframe, a trough over the Four Corners region will travel eastward and into the Plains. As a surface low begins to deepen Sunday, impulses of energy rotating around the closed low will begin to affect our region beginning on Sunday. Surges of moisture associated with a low level jet may bring inches of rainfall to southern Louisiana and Mississippi Sunday into Monday. Models are in a bit of disagreement about the total rainfall amounts but agree that there will be plenty of moisture being pushed into the region. PW values increase to 2+ inches. Dewpoints will be in the upper 60s Sunday night into Monday. WPC has QPF amounts as high as 5.5 inches bullseyed in south Mississippi in the day 4/5 timeframe. A limited risk, therefore, has been added to the HWO for flooding and in order to keep things simple in light of the current severe risks, just a note about flooding has been added to the Graphicast. This will certainly need to be adjusted as time approaches. As to severe weather, a limited risk will remain possible with strong winds aloft and favorable instability profiles suggesting organized severe storms. This system will push out gradually late Monday night through Tuesday. A closed low sweeping through the plains next Wednesday will drag a cold front through our region. This will bring another round of storms to part of the area. /10/ && .AVIATION... 00Z TAF discussion: Main concern through tomorrow regarding aviation with be the risk of thunderstorms, starting later tonight at GLH/GWO/HKS/JAN. Main threat of storms will likely hold off until early to midday tomorrow at CBM/GTR/NMM/MEI/PIB/HBG. Any storms through this period will have the risk of being severe and producing high winds and hail (and of course significant turbulence aloft in the vicinity of the storms). Expect surface winds ahead of storms tonight to generally blow from the south at 10 to 15 mph with potential gusts up to 25 mph. These south winds will continue tomorrow with winds disrupted in and around thunderstorms. brief IFR to LIFR conditions will be possible within storms with mainly MVFR ceilings on tap starting late this evening and going into at least early tomorrow at most sites. /BB/ && .PRELIMINARY POINT TEMPS/POPS...
