SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1223 AM CDT Fri Mar 15 2024 Valid 151200Z - 161200Z ...NO CRITICAL AREAS... ...Synopsis... A cutoff low will remain within the lower Colorado River Valley today. Within the northern Plains and parts of the upper Midwest, an upper-level trough will dig southward out of Canada. A surface low will deepen in southern Canada, increasing the surface pressure gradient in the northern Plains. Breezy conditions are likely across the Dakotas. RH may fall to near critical levels, particularly in pars of northern South Dakota. However, there is some uncertainty given the increase in mid/high-level clouds. Furthermore, the strongest surface winds appear probable to be displaced farther north where RH reductions are even less certain. Locally elevated conditions may occur near the North/South Dakota border. ..Wendt.. 03/15/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

WW 45 TORNADO AR OK TX 142150Z - 150500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 45 NWS Storm Prediction Center Norman OK 450 PM CDT Thu Mar 14 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Central and Southwest Arkansas Southeast Oklahoma Northeast Texas * Effective this Thursday afternoon from 450 PM until Midnight CDT. * Primary threats include... A few tornadoes possible Scattered large hail and isolated very large hail events to 2.5 inches in diameter likely Scattered damaging wind gusts to 65 mph likely SUMMARY...Thunderstorms will increase in coverage through the afternoon and evening, with a few supercells expected. Very large hail is expected to be the primary risk, but a few tornadoes are also possible. The tornado watch area is approximately along and 75 statute miles east and west of a line from 10 miles northeast of Flippin AR to 30 miles south of Texarkana AR. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. && OTHER WATCH INFORMATION...CONTINUE...WW 42...WW 43...WW 44... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 55 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 25030. ...Hart Read more

MD 0252 CONCERNING TORNADO WATCH 45...46... FOR FAR NORTHEAST TEXAS...FAR SOUTHEAST OKLAHOMA...SOUTHERN ARKANSAS
Mesoscale Discussion 0252 NWS Storm Prediction Center Norman OK 1130 PM CDT Thu Mar 14 2024 Areas affected...Far Northeast Texas...Far Southeast Oklahoma...Southern Arkansas Concerning...Tornado Watch 45...46... Valid 150430Z - 150500Z The severe weather threat for Tornado Watch 45, 46 continues. SUMMARY...The severe threat across southern Arkansas and the Ark-La-Tex is expected to continue to decrease over the next hour, and the ongoing watches will be allowed to expire at 05Z. DISCUSSION...An MCS is currently located from far northeast Texas extending east-northeastward across western and central Arkansas. The RAP suggests that instability has markedly decreased along the southern edge of the MCS over the last hour. This trend will continue, and the severe threat is expected to gradually diminish. For this reason, the ongoing watches will be allowed to expire at 05Z. It still remains possible that the severe threat could re-develop across parts of the region, but this would be later tonight. ..Broyles.. 03/15/2024 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 0250 NWS Storm Prediction Center Norman OK 0956 PM CDT Thu Mar 14 2024 Areas affected...Far Southeast Oklahoma...Far Northeast Texas...Arkansas Concerning...Tornado Watch 45... Valid 150256Z - 150500Z The severe weather threat for Tornado Watch 45 continues. SUMMARY...A severe threat will continue over the next few hours from far northeast Texas northeastward into central Arkansas. DISCUSSION...The latest mosaic radar imagery shows a broken line of strong to severe storms located across east-central Arkansas, with scattered more discrete cells from western Arkansas southward into the Ark-La-Tex. New convection appears likely to develop to the south of the ongoing storms across south-central Arkansas late this evening. In addition to moderate instability, 0-6 km shear in that areas is estimated to be near 50 knots according to the RAP. This will support continued severe storm development over the next couple of hours. Large hail and isolated wind damage will be possible with supercells. A locally greater wind-damage threat will possible ahead of short bowing line segments. In addition, low-level shear has increased across the region due to a strengthening jet near 850 mb. For this reason, a brief tornado still may occur. ..Broyles.. 03/15/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...LZK...SHV...TSA...FWD...
