SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1229 PM CDT Fri Sep 13 2019 Valid 141200Z - 151200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF MID MO AND UPPER MS VALLEYS...THE EASTERN FL PENINSULA...AND CENTRAL/SOUTHERN AZ... ...SUMMARY... Strong to severe storms may impact parts of the mid Missouri and upper Mississippi Valleys Saturday afternoon and evening. A few thunderstorms associated with a tropical system may also pose a risk for strong wind gusts and isolated tornadoes across parts of the east central Florida peninsula. Strong wind gusts are also possible across central and southern Arizona Saturday afternoon and evening. ...Synopsis... Moderate, predominantly zonal upper flow is expected across the northern tier of CONUS on Saturday with flattened ridging remaining in place over the southern CONUS. A low-amplitude shortwave trough embedded within the stronger westerly flow will move from its early period position over the northern Plains eastward through the Upper MS Valley and Upper Great Lakes. At the same time, a weak surface low associated with this shortwave is expected to move from central SD northeastward into southern MN. A cold front attendant to this surface low will move across the northern Plains for much of the day Saturday. However, the southern portion of this front is expected to slow down and eventually stall late Saturday night/early Sunday morning. Farther south, a tropical cyclone will likely be centered over the northern Bahamas early Saturday morning. This storm is expected to move gradually northwestward throughout the period. ...Mid MO Valley into the Upper MS Valley... Strong moisture advection is anticipated across the central and southern Plains on Saturday, bringing upper 60s dewpoints in the Mid MO and Upper MS Valleys by late Saturday afternoon. As a result, a moist and moderately buoyant warm sector beneath moderate vertical shear. The strongest forcing for ascent will likely remain north of the region and convergence along the front will be limited by pre-frontal veering of the surface winds. These factors are expected to keep the overall storm coverage isolated. Even so, the few storms that do develop will likely be capable of large hail and damaging wind gusts. Additionally, any robust storms near the warm front may also pose a risk for a tornado or two. Anticipated storm coverage currently precludes higher severe probabilities but upgrades may be needed in subsequent outlooks if higher storm coverage appears more likely. ...Eastern FL Peninsula - Potential Tropical Cyclone Nine... Recent intensity guidance from the National Hurricane Center suggests the cyclone will have reached Tropical Storm intensity by the beginning of the Day 2 period (i.e. 12Z Saturday). Latest forecast track keeps the center about 60-70 mi off the east-central FL coast, which keeps the strongest winds (and highest wind/tornado risk) offshore. Best chance for any damaging wind gusts and/or a tornado is currently along the immediate coastal areas of the eastern FL Peninsula during the afternoon when thunderstorms are most likely. However, any westward shift in the storm's path could result in damaging wind gusts/tornado risk farther inland. ...Central/Southern AZ... Scattered thunderstorm coverage is anticipated across central and southern AZ as low-level moisture surges northward into the region and a weak vorticity maximum approaches from northern Mexico. Expectation is for thunderstorms to develop during the early afternoon across the higher terrain, with some potential propagation into the lower deserts thereafter. Mid-level flow will be very weak but the deeply mixed boundary layer is still expected to support a few strong wind gusts and low severe probabilities have been introduced as a result. ...MAXIMUM RISK BY HAZARD... Tornado: 2% - Marginal Wind: 5% - Marginal Hail: 5% - Marginal ..Mosier.. 09/13/2019 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1127 AM CDT Fri Sep 13 2019 Valid 131630Z - 141200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SOUTHEAST LOWER MI TO NORTHERN OH... ...SUMMARY... Scattered damaging winds, a couple tornadoes, and isolated severe hail are possible across southeast Lower Michigan into northern Ohio through about 9 PM EDT. ...MI/OH/IN... An upper low over northwest ON will evolve into an open wave while moving northeastward towards James Bay, as embedded speed maxima rotate around the southeastern periphery of the low. At the surface, a cold front arcing into far southwest Lower MI to the Wabash Valley will progress east across the rest of IN/Lower MI. Thick overcast and residual stratiform rain have tempered destabilization ahead of the front across most of Lower MI, except across the southeast portion with nearly cloud-free insolation occurring from there southward across much of OH and eastern IN. Surface temperatures were already warming through the 80s and will reach the low 90s across most of OH where surface dew points should mix down into the low 60s. A confined corridor of upper 60s dew points should remain near the front and where boundary-layer mixing is not quite as pronounced across southeast Lower MI. Scattered storms are expected to develop in the next couple hours near the front, and then continue eastward across Lake Erie and parts of northern OH into this evening. Despite being on the southeast periphery of the Upper Great Lakes mid-level jet, largely unidirectional/veered wind profiles should hold effective shear to between 25-40 kts. The greatest potential for supercells will exist across southeast Lower MI where the low-level hodograph should be adequately enlarged, yielding a short-duration risk for a couple tornadoes before surface winds veer. Modest mid-level lapse rates will probably limit hail magnitudes. Scattered damaging winds should be the primary hazard with this threat likely diminishing shortly after dusk. ...Western NC into SC... Strong surface heating and lingering low-level moisture along and southwest of a reinforcing frontal surge could provide some focus for thunderstorm development this afternoon. Thermodynamic profiles will favor some risk for damaging downbursts given DCAPE values near 1000 J/kg. Minimal deep-layer shear will temper the potential for organized clustering. ..Grams/Dial.. 09/13/2019 Read more

Tropical Storm Kiko Forecast Discussion Number 5

5 years 11 months ago
Issued at 900 AM MDT Fri Sep 13 2019 000 WTPZ43 KNHC 131457 TCDEP3 Tropical Storm Kiko Discussion Number 5 NWS National Hurricane Center Miami FL EP132019 Issued by the NWS Weather Prediction Center College Park MD 900 AM MDT Fri Sep 13 2019 Kiko's convective pattern is still poorly organized. There was only a burst of convection near the estimated center overnight, and a new one is in progress. The circulation still consists of a broken low- and mid-level cloud deck with widely scattered embedded convection. Subjective Dvorak estimates from TAFB and SAB are T2.0/30 kt, while the objective estimate is near 40 kt. The initial intensity remains at 35 kt as a blend of the subjective and objective estimates. Kiko is surrounded by dry air which is probably contributing to the system's continued convective struggles. Going forward, a low shear and warm water environment with limited environmental instability looks to allow a gradual increase in intensity. The new NHC forecast shows Kiko just shy of hurricane strength in about 48 hours, which is in good agreement with the trend of the model consensus. Kiko is moving west-northwestward, or 285/9 kt, to the south of a mid-level ridge which extends along the U.S./Mexico border. This motion should continue for the next 3 days, and the track models are in good agreement on this solution. After day 3, some bifurcation of the models remain, though there are more models supporting a west to northwest track than to the north. The only substantial change to the previous forecast is a slightly slower speed in Days 4 and 5, and the forecast will stay closer to the models that support a continued west-northwest track at long range.

Miller Gulch Fire (Wildfire)

5 years 11 months ago
Due to inaccessible terrain and rugged, steep conditions, the Missoula Ranger District of the Lolo National Forest is managing the lightning-caused Miller Gulch Fire with a confine and contain strategy, utilizing point-source protection, as needed around the valley bottom and Rock Creek.The Miller Gulch Fire is located approximately 20 miles south of I-90 off of Rock Creek Road and a mile east and upslope of Bitterroot Flat Campground, and is burning on the upper third portion of a steep ridgeline.After closely evaluating terrain conditions, expected weather patterns, and considering the relatively low probability for success to fully extinguish this fire, the decision was made to take a confine and contain suppression strategy, with point protection. By using natural features, existing prescribed fire project areas, and aviation resources, this strategy will limit exposure and therefore risk to firefighters due to the hazards associated with a backcountry fire environment.Difficult...

Bodine 1 Fire (Wildfire)

5 years 11 months ago
The Bodine 1 Fire in Mitchell county was ignited from hunters in the area burning trash. Mitchell County, along with 161 other Texas counties, are currently under burn bans. The fire was approximately 28 miles SW of Colorado City, burning on a private landowners ranch. The fuel type is Mesquite-Juniper mosaic mixed w/ short grass w/ rolling topography. Due to lack of significant rainfall this summer, critically dry vegetation provided active fire behavior. This fire did not threaten any structures and firefighters continued to patrol the perimeter of the fire on Monday, 9/9. Colorado City VFD's responded first on scene, and dispatched Texas A&M Forest Service that responded with dozers and engine crews from Merkel Task Force. Additional resources included air attack, a heavy tanker, a helicopter, and a local motor grader. On Monday crews continued patrolling the scene and mopped up hot spots as necessary. Increased moisture and clouds favored cooler temperatures Monday. Relative...
