SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0620 PM CST Tue Jan 16 2024 Valid 170100Z - 171200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected tonight. ...South FL... Diminishing thunderstorm coverage is anticipated across the south Peninsula and Keys amid weak tropospheric lapse rates of 5-6 C/km and MLCAPE around 500-750 J/kg per 00Z MFL/KEY RAOBs. As a trailing cold front makes steady southeast progression, the bulk of thunderstorm activity has become confined off both coasts. With decreasing low-level convergence along the front over land, this trend is anticipated to continue. As such, thunderstorm probabilities will likely become negligible overnight. ..Grams.. 01/17/2024 Read more View the full article

MD 0076 CONCERNING FREEZING RAIN FOR PORTIONS OF NORTHWEST OR INTO FAR SOUTHWEST WA Mesoscale Discussion 0076 NWS Storm Prediction Center Norman OK 0531 PM CST Tue Jan 16 2024 Areas affected...Portions of northwest OR into far southwest WA Concerning...Freezing rain Valid 162331Z - 170400Z SUMMARY...Freezing rain will increase in both intensity and coverage across much of the Willamette Valley, the Oregon Coast Range, and the far southern Chehalis River Valley during the next 1-2 hours and persist through around 04Z. DISCUSSION...Latest water vapor imagery depicts a compact midlevel cyclone tracking eastward toward the Pacific Northwest. Strong DCVA preceding the cyclone should overspread coastal OR over the next 1-2 hours, supporting an increase in precipitation intensity and coverage across the region. The 12Z SLE observed sounding and more recent Portland ACARS soundings showed lingering dry air in the 1-5-km layer, though persistent precipitation (and related wet-bulbing) along with increasing moisture ahead of the aforementioned cyclone are likely contributing to a deep saturated layer which will further support increasing precipitation rates. In fact, freezing rain is beginning to increase in coverage across coastal OR per the latest surface observations. Low to mid 20s surface wet bulb temperatures beneath a 3-4 deg C warm nose as low as 925 mb in the Willamette Valley into the Oregon Coast Range will support complete hydrometeor melting and re-freezing at the surface, suggesting that freezing rain will be the predominant precipitation type (with pockets of sleet also possible). And, given the strengthening large-scale ascent amid a deeply saturated thermodynamic profile, freezing rain rates could exceed 0.1 inch/hour. These conditions will likely persist through around 04Z, before surface temperatures begin to warm and the dry conveyor belt accompanying the midlevel cyclone impinges on the area. ..Weinman.. 01/16/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0257 PM CST Tue Jan 16 2024 Valid 181200Z - 241200Z A progressive upper-level pattern is expected across the CONUS for the extended forecast period. A mid-level trough will eject into the Atlantic late this week as an upper-ridge builds over the Great Plains this weekend. Thereafter, another upper trough is poised to overspread the central U.S. by early next week. Surface high pressure and associated cold air will meander over the central and eastern U.S. through at least this weekend. With the passing of the upper ridge, relatively warmer, but moister low-level air will return northward from the Gulf of Mexico and overspread the south-central CONUS. The net result will be cool and/or moist surface conditions that will limit wildfire-spread potential over most of the CONUS. ..Squitieri.. 01/16/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 2000Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0148 PM CST Tue Jan 16 2024 Valid 162000Z - 171200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE FLORIDA PENINSULA... ...SUMMARY... A brief tornado or two and isolated damaging winds are possible through this afternoon across central Florida. ...Florida... Scattered storms continue to develop ahead of a front and within the moist air mass, although heating has become quite limited. Convergence is relatively weak along the boundary, which has become relatively stationary, but the uncapped air mass to the south along with favorable time of day should continue to support scattered development with MLCAPE to 1500 J/kg. Deep-layer shear is favorable for fast-moving and sustained storms with 50-60 kt, and winds do veer with height especially over the eastern part of the Peninsula. As such, a storm or two could become a supercell this afternoon with the risk of a tornado, but overall coverage of severe storms should remain isolated given minimal large-scale support and gradually veering low-level winds. ..Jewell.. 01/16/2024 .PREV DISCUSSION... /ISSUED 1001 AM CST Tue Jan 16 2024/ ...Central FL this afternoon... A broad midlevel trough from the Ozarks to the OH Valley will progress eastward to the Atlantic coast by late tonight, as an associated surface cold front moves southeastward across central/south FL. A subtle/embedded speed max over the northern Gulf of Mexico will move over north FL this afternoon, and this will help focus thunderstorm development through the day across central FL, both along and south of the cold front. Midlevel lapse rates will not be steep, but some cloud breaks north of ongoing convection and boundary-layer dewpoints in the low 70s will contribute to MLCAPE near 1000 J/kg ahead of the cold front, and somewhat larger buoyancy along the southern fringes of the ongoing convection in central FL. The storms west of Tampa have shown some increase in intensity along the front, and additional storm development is possible along the southern periphery of the ongoing storms across central FL. Deep-layer vertical shear/hodograph length will be sufficient for some organized/rotating storms, while low-level hodograph curvature/SRH will remain relatively larger through early afternoon and begin to decrease by mid-late afternoon as low-level flow veers. The net result will be the potential for line segments or supercells capable of producing isolated wind damage. A brief tornado or two will also be possible, focused a little more toward the Atlantic coast where low-level shear will be modestly stronger through more of the afternoon.

SPC Day 2 Fire Weather Outlook Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0146 PM CST Tue Jan 16 2024 Valid 171200Z - 181200Z ...NO CRITICAL AREAS... The previous forecast (see below) remains on track, with no changes or additions made. ..Squitieri.. 01/16/2024 .PREV DISCUSSION... /ISSUED 1149 PM CST Mon Jan 15 2024/ ...Synopsis... An embedded midlevel impulse accompanied by strengthening westerly flow aloft will cross the central Rockies during the day, promoting lee cyclogenesis over the central High Plains. Through the afternoon, the lee cyclone should evolve southward into the southern High Plains, where warmer surface temperatures and reduced static stability will be in place. In response, breezy surface winds are expected along/south of the lee cyclone over the southern High Plains, where downslope warming/drying will contribute to modest RH reductions. The combination of 15-20 mph west-southwesterly surface winds and 15-25 percent RH may yield locally elevated fire-weather conditions; however, marginal fuels and the localized nature of the threat preclude Elevated highlights. ...Please see www.spc.noaa.gov/fire for graphic product...
