URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 156 NWS Storm Prediction Center Norman OK 540 PM CDT Sun Apr 20 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Eastern Arkansas Far Southeast Missouri * Effective this Sunday afternoon from 540 PM until Midnight CDT. * Primary threats include... A few tornadoes possible Scattered damaging wind gusts to 70 mph possible Isolated large hail events to 1.5 inches in diameter possible SUMMARY...Severe storms including supercells are expected to move into the region this evening, including tornado potential aside from large hail and damaging winds. The tornado watch area is approximately along and 45 statute miles east and west of a line from 35 miles northeast of Walnut Ridge AR to 25 miles southwest of Monticello AR. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). 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 154...WW 155... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500.

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0439 PM CDT Sun Apr 20 2025 Valid 221200Z - 281200Z Across the CONUS, mid-level flow will become zonal and weaken slightly over the next several days before a more amplified pattern emerges mid to late week next week. Lee troughing and downslope winds will increase from the Rockies to the Southwest. Dry conditions and ridging aloft are also expected over the eastern US. This will tend to support an increase in fire-weather concerns over the extended forecast period. ...Southwest to the High Plains... As flow aloft begins to increase with the more amplified flow pattern, gusty winds and dry conditions are expected over much of the western US. Lee troughing and gusty downslope winds are likely over the Rockies and High Plains through early next week. Dry and breezy conditions are expected over the Southwest and southern High Plains, possibly extending into WY/CO. Given relatively dry fuels, this will support elevated fire-weather concerns. Dry and breezy conditions are also possible over the Great Basin, though fuels here remain less receptive. A strong cold front will then move south midweek, bringing cooler temperatures and limiting broader fire-weather potential over the Plains. There remains some uncertainty on the extent of fire-weather conditions late next week into next weekend, as the cold front is likely to usher in a cooler air mass over the southern High Plains and parts of the Southwest. More sheltered areas in the southern Great Basin and western NM may still have several days of dry and breezy conditions as the main western US trough and flow aloft shift eastward. However, confidence in the evolution of the upper-air pattern remains limited, and no additional probabilities have been added pending uncertainties on drying fuels. ...Southeast... Subtropical ridging is excepted to gradually build through the extended forecast period, keeping much of the Southeastern US warm and relatively dry. Winds beneath the ridge should also remain fairly light. Ongoing drought is likely to persist, potentially supporting some fire-weather concerns through much of next week. This is especially so over parts of FL where fuels are very dry and easterly winds may reach 10-15 mph occasionally. ..Lyons.. 04/20/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

A strong cold front will then move south midweek, bringing cooler temperatures and limiting broader fire-weather potential over the Plains. There remains some uncertainty on the extent of fire-weather conditions late next week into next weekend, as the cold front is likely to usher in a cooler air mass over the southern High Plains and parts of the Southwest. More sheltered areas in the southern Great Basin and western NM may still have several days of dry and breezy conditions as the main western US trough and flow aloft shift eastward. However, confidence in the evolution of the upper-air pattern remains limited, and no additional probabilities have been added pending uncertainties on drying fuels. ...Southeast... Subtropical ridging is excepted to gradually build through the extended forecast period, keeping much of the Southeastern US warm and relatively dry. Winds beneath the ridge should also remain fairly light. Ongoing drought is likely to persist, potentially supporting some fire-weather concerns through much of next week. This is especially so over parts of FL where fuels are very dry and easterly winds may reach 10-15 mph occasionally. ..Lyons.. 04/20/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0439 PM CDT Sun Apr 20 2025 Valid 221200Z - 281200Z Across the CONUS, mid-level flow will become zonal and weaken slightly over the next several days before a more amplified pattern emerges mid to late week next week. Lee troughing and downslope winds will increase from the Rockies to the Southwest. Dry conditions and ridging aloft are also expected over the eastern US. This will tend to support an increase in fire-weather concerns over the extended forecast period. ...Southwest to the High Plains... As flow aloft begins to increase with the more amplified flow pattern, gusty winds and dry conditions are expected over much of the western US. Lee troughing and gusty downslope winds are likely over the Rockies and High Plains through early next week. Dry and breezy conditions are expected over the Southwest and southern High Plains, possibly extending into WY/CO. Given relatively dry fuels, this will support elevated fire-weather concerns. Dry and breezy conditions are also possible over the Great Basin, though fuels here remain less receptive.
