The severe weather potential is still on track for tonight and is still increasing in danger and potential. I don’t want to be over hyping for you guys and saying this storm will be pretty bad, but by the looks of it, it will be bad SOMEWHERE. So, I want y’all, due to the increase to a MODERATE risk, to take precautions because we have had an increase in the tornado risk and wind risk so:
- Move lose outdoor furniture under your awning or patio
- know where your safe place is in case of tornado or high winds (Yes, go to your safe place during severe 58+ MPH winds)
- STAY WEATHER AWARE For the Severe Weather Danger has Increases
And that’s all I really have. No need to hype, just was being serious with y’all…. The Severe Weather Danger has Increases
.We have the Ingredients, we have Risks, we’ll see what happens. The timing is still between from 8 PM past into Midnight. I expect SPC to issue a tornado watch or severe thunderstorm watch soon for North Texas, East Texas, Oklahoma, and maybe parts of Arkansas.
stay tuned
SPC AC 281226 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0726 AM CDT Tue Apr 28 2020 Valid 281300Z - 291200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF EASTERN OKLAHOMA...FAR WESTERN ARKANSAS AND NORTHEAST TEXAS... ...SUMMARY... Widespread severe thunderstorms are expected to develop this afternoon and evening across parts of the Ozarks into the southern Plains. Damaging winds with gusts possibly exceeding 65 mph, very large hail and a few tornadoes can be expected. ...Southern Plains/Arklatex/Ozarks/Mid to Upper Mississippi Valley... An upper-level trough will dig southeastward from the northern Plains into the central Plains today. An associated mid-level jet will dive southeastward into the central Plains. The leading edge of the stronger mid-level flow associated with the jet will overspread a corridor of maximized low-level moisture located from northeast Texas north-northeastward into the Ozarks. Moisture advection ahead of the system, will increase surface dewpoints into the 60s F across most of Oklahoma, Arkansas and Missouri by afternoon. In response to surface heating, the moisture will contribute to moderate destabilization with MLCAPE values reaching the 2000 to 4000 J/kg range across parts of the moist sector. Thunderstorms are forecast to first initiate to the south of a surface low on the northern edge of the moist airmass in eastern Iowa around midday. Thunderstorms will then likely develop south-southwestward along a cold front from northern Missouri into southeast Kansas during the afternoon. This convection is forecast to grow upscale as a squall line organizes and moves south-southeastward across the southern Plains and Ozarks. The moisture and instability combined with strong deep-layer shear will be favorable for severe thunderstorms across a widespread area. RAP forecast soundings along the most unstable parts of the front during the late afternoon increase MLCAPE into the 3000 to 4000 J/kg range and show 0-6 km shear generally from 30 to 40 kt. This environment will support supercells with large hail, especially early in the event before the squall line becomes organized. The potential for supercells with hailstones greater than 2 inches in diameter is expected to be greatest from far southeast Kansas into central Oklahoma and far northern Texas where instabilty is forecast the strongest. Supercells early in the event may also be accompanied by a tornado threat. The tornado threat is expected to be greatest across eastern Oklahoma and far western Arkansas where a low-level jet will strengthen during the late afternoon and early evening. Forecast soundings in this area increase 0-3 km storm relative helicities into the 250 to 400 m2/s2 range suggesting a more substantial tornado threat will be possible. For this reason, have added a 10 percent tornado probability contour across parts of the moderate risk area. Increasing low-level convergence during the early evening along the front should gradually result in the development of a nearly continuous squall line. This squall line is forecast to become more organized as it moves southward across southwest Missouri, western Arkansas and east-central Oklahoma. Wind damage will be likely along the leading edge of the squall line. Wind gusts over 65 kt will be possible ahead of the faster moving parts of the squall line. A few tornadoes may also occur with rotating cells embedded in the line. A widespread wind damage threat should continue into parts of north-central and northeast Texas during the mid to late evening before a gradual weakening takes place due to overnight decreasing instability. ..Broyles/Guyer.. 04/28/2020
