(4/5) N Plains Blizzard -Rain changes to ice (with light accretions) and then to snow Fri night/early Sat -Narrow, heavy band of snow in western MN, with 6-10" possible, sharp cut-off outside this band -Wind gusts up to 60 mph create whiteout conditions, blowing/drifting

(5/5) Wind Threat -Widespread wind gusts 40-60 mph across the central/eastern US -Destructive wind (widespread 60-80+ mph gusts), wildfire, and dust storm continues across the S Plains into the evening, tapering off overnight

Another strong low bringing impactful weather for mid-week: -Sct'd severe storms, particularly in the Midwest -Blizzard from KS to WI, narrow band of heavy snow -Widespread gusty winds 40-60 mph; pockets of 60+ mph gusts E NE/TX panhandle -Enhanced dust/fire conditions S Plains

(1/2) Another storm system is working across the country today into Monday. Significant wintry impacts have already been felt from the Great Lakes to Upper Midwest, with more snow/ice to come. South of the surface low, areas of heavy rain and severe thunderstorms will be possible

(2/2) A squall line will continue to pose a damaging wind/tornado threat in the Great Lakes, while supercells developing in the mid-MS Valley pose a higher tornado threat; primarily hail threat in Tex-Ark-La before congealing to a QLCS. Damaging wind/tornado threat East Coast Mon

(1/4) Very active pattern sets up tmrw through the wknd -Strong low brings widespread winter, severe impacts -Longwave trough stalls over the central US -Shortwaves follow jet stream from S Plains to Great Lakes -Stalled frontal boundary after first low provides focus for storms

(2/4) FLOOD THREAT The flood threat is the biggest threat from this setup. Multiple rounds of heavy rain/storms will train over the same corridor from AR to OH, bringing widespread amounts of several inches. Combined with already saturated grounds, widespread flooding is likely!

(3/4) SEVERE THREAT -Conditional event along the dryline Tues night in KS/OK: all hazards poss. -Wind/hail threat further north/east Tues night -Surging instability overlaps strong shear/lift MS/OH Valleys Wed; all hazards poss. -Lower threat continues through wknd

(4/4) WINTER THREAT -Moisture overlaps sufficiently cold air in Dakotas/MN for several inches of heavy, wet snow Tues into Wed -Snow/ice spread east from northern Great Lakes to northern New England, with generally lesser impacts

(1/4) Active pattern beginning to get going across the US, and impacts will be no joke. -Widespread, significant flood threat after multiple rounds of heavy rain for several days -Substantial severe weather threat, particularly tonight/Wed -Winter storm across the northern US

(2/4) FLOODING *Very significant flooding, perhaps rivaling historic events like April 2011, is likely in the MS/OH Valleys* -Widespread rain totals up to a foot, iso up to 20", from AR to W KY -Major areal, river/creek flooding -Flash flooding as storms train over the same areas

(3/4) SEVERE -A few supercells forming in OK/KS pose a sig tor/hail/wind threat tonight -MCS in NE KS, NW MO with a wind/hail threat tonight -Widespread storms, including supercells, with all hazards MS/OH Valleys Wed; could extend to Great Lakes -Lower threats continue into wknd

(4/4) WINTER -Snow continues tonight through Wed eastern Dakotas/northern MN, with several inches expected -Highest totals with lake enhancement in northeast MN -Lighter snow/ice spreads east into the Great Lakes and northern New England Wed/Wed night

Sig severe event on track today: -Numerous storms, including some supercells, pose an all-hazards threat from IN to AR -Greatest tornado threat Mid-MS Valley -Very large hail to 3" possible with any supercells -QLCS with widespread damaging wind, tornado threat well into tonight

Potential for a catastrophic, historic flood event MS/OH Valleys today through Sat -Multiple rounds of heavy rain/storms -Widespread totals up to a foot; iso totals to 20" -Previously saturated ground exacerbates threat -Major river/creek flooding, widespread areal/flash floods

Very active sequence continues: -Damaging winds/hail possible from TX to Mid-Atlantic today; narrow corridor of enhanced tornado threat -Widespread severe weather/supercells possible again tmrw Ark-La-Tex -Threat shifts slightly south/east Sat -Sig flood threat continues now-Sat

Severe weather and significant flooding continue into the weekend -Numerous storms pose an all hazards threat around AR, including tornadoes (some strong) today -Squall line pushes east Sat/Sun with winds/a few tornadoes, but some supercells with hail/tors possible around N LA

(1/3) Another active stretch of weather looks to kick off tonight through the weekend. A low pressure will bring a cold front that will stall across the central US, bringing rounds of storms and heavy rain. The front will creep south and east Fri/Sat before another system Sun

(2/3) Multiple days of a severe threat -Sct'd storms, including some supercells, tonight in the Midwest -Renewed storm threat along the front Fri/Sat with mostly a hail/wind threat -Potential for an all hazards threat Sun Ozarks to Mid-MS Valley

(3/3) Flooding threat -Large swath of 1"+ from TX to OH, with widespread 3-5" likely from OK to IL -Lower amounts, further north and west than extreme flood event early in April -Added moisture to MS watershed renews flood threat, particularly in rivers/streams
