SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0256 PM CDT Sat Apr 01 2023
Valid 021200Z - 031200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN AND
CENTRAL HIGH PLAINS...
Expanded the Elevated and Critical delineation northward across the
Colorado Front Range where fuels have started to dry and winds of 15
to 20 mph are expected Sunday.
In addition, expanded the Elevated area to the west across eastern
Arizona and western New Mexico where fuels have started to dry and
winds of 25 mph with single digit relative humidity is expected.
Otherwise, the ongoing forecast remains on track.
..Bentley.. 04/01/2023
.PREV DISCUSSION... /ISSUED 0159 AM CDT Sat Apr 01 2023/
...Synopsis...
A shortwave impulse will move across New Mexico and Texas on Sunday
bringing increasing westerly flow aloft. Elevated to Critical fire
weather conditions will be possible across eastern New Mexico and
western Texas.
...Eastern New Mexico and Western Texas...
Winds will likely begin to mix early Sunday morning across portions
of western Texas and eastern New Mexico as the shortwave approaches.
Very dry conditions will already be in place with temperatures
warming into the afternoon. Relative humidity reductions to around
10 percent (locally as low as 5-7 percent) will be possible with
sustained winds around 15-20 mph (locally up to 25 mph). This in
combination with ERCs approaching the 70-80th percentile after
several days of drying support a Critical delineation across eastern
New Mexico and western Texas from the Texas Panhandle south to Trans
Pecos and eastward to Caprock.
...Central New Mexico and the Oklahoma Panhandle southward to the
Rolling Plains of Texas...
A broader region of Elevated fire weather conditions will be
possible across areas near and south of the Albuquerque area as well
as further east into the Oklahoma Panhandle and Rolling Plains of
Texas. Winds within this region are less certain, though areas of
sustained winds up to 15-20 mph will be possible with locally
Critical fire weather concerns. Potential expansion of the Critical
area may be needed in further updates.

WW 107 SEVERE TSTM NY PA 011825Z - 020000Z
URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 107
NWS Storm Prediction Center Norman OK
225 PM EDT Sat Apr 1 2023
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Central New York
Central and Eastern Pennsylvania
* Effective this Saturday afternoon and evening from 225 PM until
800 PM EDT.
* Primary threats include...
Scattered damaging wind gusts to 65 mph possible
SUMMARY...A fast-moving band of storms will pose mainly a damaging
wind risk this afternoon.
The severe thunderstorm watch area is approximately along and 110
statute miles north and south of a line from 45 miles north
northwest of State College PA to 20 miles northeast of Wilkesbarre

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1223 PM CDT Sat Apr 01 2023
Valid 021200Z - 031200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS DURING THE DAY
ACROSS NORTH TX...
...SUMMARY...
Occasional large hail, isolated damaging winds, and a couple of
tornadoes will be possible during the day tomorrow, mainly across
north Texas.
...North TX and vicinity through the day...
In the wake of a pronounced midlevel trough now moving over the OH
Valley/lower Great Lakes, a front will stall along the Gulf coast.
Upstream, a shortwave trough now near northern Baja will progress
eastward to the southern Plains tomorrow afternoon. In response to
the approach of this trough and increasing westerly flow across the
Rockies, lee cyclogenesis across the southern High Plains will
result in strengthening southerly low-level flow and northward
moisture advection during the day across TX. The increasing
low-level moisture beneath the eastward extent of a elevated mixed
layer plume will support substantial destabilization during the day
across north TX.
Clusters of mainly elevated storms are probable during the day in
the zone of stronger low-level warm advection across northwest TX
into southern OK, with sufficient MUCAPE/lapse rates for occasional
large hail. Farther south, there will be a few hour window of
opportunity for supercells rooted near or at the surface within the
southern fringe of the stronger forcing for ascent, close to the
surface warm front around mid afternoon. Mid-upper 60s
boundary-layer dewpoints and surface heating in cloud breaks and
midlevel lapse rates of 7-8 C/km will drive MLCAPE up to 1500 J/kg
along the warm front, with sufficient deep-layer shear/hodograph
length and low-level shear/hodograph curvature for supercells with
all hazards. These threats will be focused along the warm front
from about 20-00z, with the threat for surface-based supercells
diminishing during the evening with passage of the midlevel trough.
Otherwise, clusters of slightly elevated storms will spread eastward
toward northwest LA/southwest AR and slowly weaken early tomorrow
night.

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1137 AM CDT Sat Apr 01 2023
Valid 011700Z - 021200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN/CENTRAL
HIGH PLAINS...
The forecast remains on track and no changes were necessary. Some
elevated conditions are already present across southeast Colorado
and vicinity. Sunny skies will allow additional warming and deep
mixing through the afternoon with critical conditions likely
developing by 19-20Z.
..Bentley.. 04/01/2023
.PREV DISCUSSION... /ISSUED 1248 AM CDT Sat Apr 01 2023/
...Synopsis...
A belt of strong westerly flow aloft will overspread the Pacific
Northwest and Northern Rockies on Saturday as an embedded shortwave
moves eastward across Arizona and into New Mexico. East of the
Rockies, lee troughing will develop in response with increased south
to southwesterly flow across the Central and Southern High Plains
across a very dry post-frontal air mass. Elevated to Critical fire
weather will be possible. Dry conditions will extend further south
and east but lighter winds will preclude the need for expansion of
any areas.
...Eastern CO, Northeastern NM, northwest TX, western OK
Panhandle...
The Critical area was maintained with this update. HREF guidance
still shows the highest conditional probability of Critical
conditions across far southeastern Colorado, northeastern New
Mexico, west Texas, and the Oklahoma Panhandle. Confidence in
relative humidity reductions to around 10-15 percent within this
region is high. Some question remains in the extent of the stronger
winds. As such, ensemble guidance was leveraged to narrow down the
most likely region of dry/windy overlap with the driest fuels. It is
possible that locally Critical fire weather conditions may occur
within the broader Elevated region. Minor adjustments were made to
expand the Elevated area across the eastern edge further into
Oklahoma and Texas.
...Far West Texas near Stockton Plateau and Edwards Plateau...
Localized Elevated to Critical fire weather conditions will be
possible across the Stockton and Edwards Plateau Saturday afternoon.
Given the localized and largely terrain driven nature of any
Critical conditions, no area was included with this update. However
areas of Elevated to Critical fire weather conditions will be
possible. Drying fuels in this region will likely support fire
spread.

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1134 AM CDT Sat Apr 01 2023
Valid 011630Z - 021200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS THE
NORTHEAST STATES INCLUDING PARTS OF PA/NY/OH/NJ...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SOUTHEAST
STATES...
...SUMMARY...
Damaging winds and a couple tornadoes will be possible across parts
of the Northeast this afternoon and evening. Isolated to scattered
damaging winds and a tornado or two remain possible across parts of
the Southeast through the afternoon.
...Northeast States...
Parts of the region have been upgraded to a categorical Enhanced
Risk. This is related to an initial concern for increasingly
organized/fast-moving linear low-topped convection moving from
eastern Ohio into western portions of Pennsylvania/New York early
this afternoon. Although the immediately preceding air mass is not
overly moist, ample insolation/heating via cloud-free skies in
conjunction with a strong wind field and regionally observed steep
lapse rates will support scenario for potentially widespread
damaging winds aside from some hail.
Farther east, richer boundary-layer moisture will persist closer to
the coastal plain across the Delaware/Lower Hudson Valleys. While
pervasive cloud cover persists at midday (roughly within 75-100
miles of the Atlantic Coast at 16z), steady clearing is expected
this afternoon based on radar/satellite trends. Environment will
support both a conditional supercell environment as well as
persistence/potential rejuvenation of the upstream fast-moving
convective line. If a few supercells materialize, tornadoes, hail,
and damaging winds would all be possible, and damaging winds are
otherwise probable with the inbound convective line roughly centered
in the 21z-01z time frame for eastern Pennsylvania, New Jersey,
southern New York/NYC Metro vicinity.
...Southeast States...
Deep-layer flow will gradually trend more westerly with time as the
strong upper low advances east across the Ohio Valley. Pre-frontal
convection currently extends from central Georgia to southern
Alabama at midday, and this will continue to advance east-southeast
through the day. While the primary large-scale forcing will spread
well north of this region, deep-layer flow will be strong and
organized clusters/short-line segments are expected. Damaging winds
should be the primary concern, though some risk for a tornado or two
exists as well.

Areas affected...Southeast Iowa
Concerning...Tornado Watch 93...
Valid 312059Z - 312130Z
CORRECTED FOR AREAS AFFECTED
The severe weather threat for Tornado Watch 93 continues.
SUMMARY...Likely strong tornado (upper EF2 to EF3) ongoing northeast
of Ottumwa. The downstream environment will continue to support the
potential for a strong tornado.
DISCUSSION...A supercell northeast of Ottumwa has shown increasing
low-level rotation with a tornado recently confirmed. Current VROT
observations from KDMX are around 60 kts. Given the environment,
this would suggest a strong tornado (EF2-EF3) is likely ongoing. The
deepening surface low and continued backed surface winds in eastern
Iowa will continue to support a strong/intense tornado threat as
this storm continues to the north and east.

Areas affected...Northern Illinois...southern Wisconsin...and
northwest Indiana.
Concerning...Tornado Watch 96...
Valid 312050Z - 312145Z
The severe weather threat for Tornado Watch 96 continues.
SUMMARY...The risk for hail and tornadoes will continue across WW93
as storms approach the Chicago metro.
DISCUSSION...A cluster of supercells across north-central IL should
continue northeastward reaching the western Chicago Suburbs and
southern WI over the next 1-2 hours. Numerous reports of severe hail
have been received this afternoon and should continue as storms
track northeastward. Around 1000 J/kg of MUCAPE and 60+ kt of
effective shear strongly favor hail production with a supercell
mode. A risk for tornadoes may also evolve as storms approach the
more strongly sheared warm frontal zone over southern WI and
northeastern IL. Though this is more uncertain owing to more
marginal surface dewpoints in the mid to upper 50s F.

MD 0404 CONCERNING TORNADO WATCH 94... FOR AR INTO PARTS OF THE MS/TN VALLEYS
Mesoscale Discussion 0404
NWS Storm Prediction Center Norman OK
0342 PM CDT Fri Mar 31 2023
Areas affected...AR into parts of the MS/TN Valleys
Concerning...Tornado Watch 94...
Valid 312042Z - 312215Z
The severe weather threat for Tornado Watch 94 continues.
SUMMARY...The threat for tornadic supercells will continue into the
early evening, with a continued risk of strong tornadoes. Downstream
watch issuance may be needed prior to 00Z.
DISCUSSION...A cluster of supercells is ongoing at 2030 UTC near and
east of Little Rock, with the lead supercell having earlier produced
an apparent strong tornado near/north of Little Rock. This supercell
cluster will continue to move east-northeastward toward the MS
River, with additional supercell development expected with
convection now developing across western AR. The lead supercell
cluster will be moving through the strongest low-level shear
environment into early evening, with the low-level jet expected to
become maximized near the MS Valley region. Strong tornadoes will
remain possible with this cluster into eastern AR, western TN, and
northwest MS.
Farther west, some veering of low-level flow has been noted, but
moderate buoyancy (MLCAPE of 1500-2000 J/kg) and very strong
deep-layer shear (effective shear of 70+ kt) will continue to be
very favorable for discrete supercells. All severe hazards will
remain possible with any supercells that develop across western AR
and move east-northeastward into early evening, with low-level
flow/shear remaining sufficient to support a strong tornado threat
with any longer-lived supercells.
The severe thunderstorm threat will begin to spread east of WW 94 by
early evening, and downstream watch issuance will likely be needed
prior to 00Z.

MD 0403 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHEASTERN MN AND SOUTH-CENTRAL WI
Mesoscale Discussion 0403
NWS Storm Prediction Center Norman OK
0338 PM CDT Fri Mar 31 2023
Areas affected...southeastern MN and south-central WI
Concerning...Severe potential...Watch unlikely
Valid 312038Z - 312245Z
Probability of Watch Issuance...20 percent
SUMMARY...The threat for large hail may develop and spread northward
from northern IA into southeastern MN. Locally severe thunderstorms
may also eventually spread into south-central WI towards this
evening.
DISCUSSION...Water-vapor imagery shows the mid-level low over the
north-central Great Plains gradually moving towards the upper MS
Valley. Strong large-scale ascent has overspread the northern
periphery of the warm sector over north-central IA. Scattered
strong to severe thunderstorms will likely spread downstream towards
the northeast within an adequately unstable (500-1500 J/kg MUCAPE)
and strongly sheared environment to the north of the warm front. As
this surface-based thunderstorm activity over northern IA moves
across and north of the warm front, the storms will become elevated
but a few of the stronger storms may pose a risk for large hail. At
this time the threat appears localized but convective trends will be
monitored.
