SPC MD 154MD 0154 CONCERNING SEVERE THUNDERSTORM WATCH 17... FOR NORTHERN INDIANA INTO SOUTHERN MICHIGAN 
Mesoscale Discussion 0154 NWS Storm Prediction Center Norman OK 0637 PM CST Fri Mar 06 2026
Areas affected...Northern Indiana into southern Michigan
Concerning...Severe Thunderstorm Watch 17...
Valid 070037Z - 070230Z
The severe weather threat for Severe Thunderstorm Watch 17 continues.
SUMMARY...A squall line will continue east across northern Indiana and southern lower Michigan for the next couple of hours before gradually weakening. Damaging gusts remain the primary threat.
DISCUSSION...Latest MRMS and GOES IR imagery continue to show new updraft development within a squall line draped from southern MI into northwest IN, and local radar imagery continues to show a few bowing segments within the line. Regional VWPs and latest RAP mesoanalysis continues to show a strongly sheared environment in place across the region with 0-3 km BWD values on the order of 30-40 knots and 40-50 knots winds within the lowest kilometer. This kinematic environment will continue to support the potential for organized/bowing segments within the line with an attendant threat for severe/damaging winds - especially with any meridionally-oriented segments. With time, a gradual weakening trend is expected as the squall line outpaces the axis of better surface-based buoyancy draped from western IL into northern IN. The onset of nocturnal cooling will further contribute to an overall reduction in convective intensity in the coming hours.

SPC MD 155MD 0155 CONCERNING TORNADO WATCH 16... FOR EASTERN NEBRASKA INTO WESTERN IOWA 
Mesoscale Discussion 0155 NWS Storm Prediction Center Norman OK 0712 PM CST Fri Mar 06 2026
Areas affected...Eastern Nebraska into western Iowa
Concerning...Tornado Watch 16...
Valid 070112Z - 070315Z
The severe weather threat for Tornado Watch 16 continues.
SUMMARY...Elevated thunderstorms to the north of a cold front will continue to pose a large to very large hail threat for the next several hours.
DISCUSSION...Elevated thunderstorms developing to the north of a surging cold front have produced hail stones ranging from 1 to 2 inches over the past hour. Although radar presentation of these cells has been somewhat meager, the 00z OAX sounding sampled 1250 J/kg MUCAPE above the frontal surface and an elongated hodograph characterized by effective bulk shear on the order of 50 knots. This environment is very favorable for splitting supercells capable of producing large/very large hail. Per latest RAP mesoanalysis estimates, this environment extends eastward into western IA, and additional cells are noted developing within the post-frontal regime across eastern NE/western IA. These trends suggest that the threat for large hail is likely increasing, though it remains somewhat unclear how long storm mode will remain discrete/semi-discrete downstream. Regardless, additionally watch issuance may be needed in the coming hours to address this threat if the developing cells remain highly efficient at hail production.

SPC MD 156MD 0156 CONCERNING TORNADO WATCH 15...18... FOR NORTHEAST OKLAHOMA TO WEST-CENTRAL MISSOURI 
Mesoscale Discussion 0156 NWS Storm Prediction Center Norman OK 0743 PM CST Fri Mar 06 2026
Areas affected...Northeast Oklahoma to West-Central Missouri
Concerning...Tornado Watch 15...18...
Valid 070143Z - 070315Z
The severe weather threat for Tornado Watch 15, 18 continues.
SUMMARY...Supercell threat, with isolated tornadoes, continues this evening.
DISCUSSION...Complex mode of convection has evolved from northeast OK into west-central MO. Strong low-level warm advection is noted along this corridor, coincident with the LLJ. VWP data from INX/SGF/EAX all exhibit 0-3 SRH values in excess of 400 m2/s2, and ample buoyancy was noted on the 00z soundings from SGF/TOP/OUN. OUN was particularly noteworthy with 2100 J/kg MLCAPE and negligible inhibition. Latest radar data depicts at least two long-lived supercells over northeast OK, embedded within a broader mixed-mode elongated convective band. This activity will continue to spread/develop northeast, along with an attendant risk for tornadoes and perhaps some large hail.

SPC MD 151MD 0151 CONCERNING HEAVY SNOW FOR NORTHEAST COLORADO INTO WESTERN NEBRASKA 
Mesoscale Discussion 0151 NWS Storm Prediction Center Norman OK 0436 PM CST Fri Mar 06 2026
Areas affected...Northeast Colorado into western Nebraska
Concerning...Heavy snow
Valid 062236Z - 070230Z
SUMMARY...Moderate to heavy snow bands will likely continue into the early evening hours across northeast Colorado into parts of western Nebraska. Snowfall rates may exceed 1 inch/hour under the more persistent bands.
DISCUSSION...Transient snow bands have been evident in regional radar mosaics over the past couple of hours across northeast CO and western NE. ASOS/AWOS observations under these bands have been reporting visibility reductions down to 1/4 mile at times under the heavier bands. Despite winds of 20-25 mph, blowing snow model output suggests these visibility reductions are mainly attributable to heavy snowfall rates given temperatures in the upper 20s/low 30s.
Heading into the evening hours, strong synoptic ascent within the left-exit region of a passing upper jet coupled with more focused frontogenetical lift between 850-700 mb will support a continuation of at least transient heavy snow bands across northeast CO and into parts of western NE for the next several hours. Although some areas remain above freezing, an influx of colder air behind a passing cold front should allow for temperatures through the lowest couple of kilometers to fall below freezing and support moderate to heavy snowfall rates later this evening. Based on recent observations and latest model guidance, snowfall rates up to one inch/hour appear likely under the heavier, more persistent snow bands.
