MD 0073 CONCERNING WINTER MIXED PRECIPITATION FOR PARTS OF THE MID ATLANTIC INTO SOUTHERN NEW ENGLAND Mesoscale Discussion 0073 NWS Storm Prediction Center Norman OK 0749 AM CST Tue Jan 16 2024 Areas affected...Parts of the Mid Atlantic into southern New England Concerning...Winter mixed precipitation Valid 161349Z - 161745Z SUMMARY...Locally moderate winter precipitation rates will spread northeastward this morning, with some modest ice accretion possible where freezing rain persists. DISCUSSION...A surface low currently off of the Mid Atlantic coast is forecast to gradually deepen as it moves northeast toward coastal southern New England this morning. Multiple waves of light to locally moderate precipitation are ongoing and will continue to spread northeastward in conjunction with the surface low. While interior portions of the Northeast will likely continue to see snow (with generally light to moderate rates) this morning, low-level warm advection will support a transition from snow to sleet across parts of southern New England, with freezing rain persisting over portions of the Mid Atlantic region. As the low deepens offshore, a modest uptick in precipitation intensity will be possible through the morning. While rates will likely remain light to locally moderate, antecedent cold conditions (with temperatures initially in the 20s F) may result in relatively efficient ice accretion in areas that transition to freezing rain. Pockets of moderate sleet/snow will also be possible into parts of southern New England. Low-level warm advection will support a gradual transition to rain along the Mid Atlantic and southern New England coasts, but subfreezing temperatures may persist inland through the morning. ..Dean.. 01/16/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC 1300Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0637 AM CST Tue Jan 16 2024 Valid 161300Z - 171200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN CENTRAL FLORIDA... ...SUMMARY... A couple brief tornadoes and isolated damaging winds are possible this morning into the afternoon over parts of the Florida Peninsula. ...Synopsis... Broadly cyclonic flow in mid/upper levels will be maintained over most of the CONUS, as a large cyclone meanders over the southern Hudson Bay/northern ON region. A basal shortwave trough was apparent in moisture-channel imagery from Lower MI across southern IL to the KS/OK border vicinity. By 00Z, this perturbation is expected to elongate further and pivot to northern NY, PA, WV, parts of KY/TN, and AR. By 12Z tomorrow, the trough should be over or just offshore of the coast from New England to northeastern NC, arching inland to the TRI area. At the surface, 11Z analysis showed two primary fronts: 1. A warm to quasistationary boundary extended from a low near Cape San Blas southeastward across central FL to a weak low near XMR, then northeastward approximately along the western part of the Gulf Stream past the NC Outer Banks. This boundary should drift northward over land through much of the day, potentially reaching north-central FL before being overtaken by the next front. 2. An Arctic cold front was drawn from the San Blas low northeastward to another low between HKY-AVL, and southwestward across the central Gulf. This front will move offshore of all the Atlantic Coast by 00Z, except central FL. By 12Z, the cold front should clear the entire FL Peninsula and Keys. ...FL Peninsula... Widely scattered to scattered thunderstorms are expected to move roughly eastward across the area, both from the Gulf on either side of the southern front, and from development over land along and south of that boundary. Isolated damaging to severe gusts are possible -- mainly near and south of the southern front where surface-based inflow is expected. A tornado also may occur in the same regime -- especially closer to the Atlantic Coast where more potential exists for storm-scale interaction with sea-breeze and/or favorably aligned outflow boundaries. For this outlook cycle, unconditional severe probability bins overall are kept at marginal categorical level, but appear nonuniform within that. Overall, they would appear somewhat greater to the east and lower to the west, if continuous/heatmap-style coloring were available. Activity over the central and especially eastern parts of the peninsula -- along and south of the southern then combined front -- will have access to a richly moist boundary layer with the longest time frame for diurnal destabilization of the inflow layer. Somewhat muted diabatic heating through cloud cover will slow the pace of destabilization, but still yield favorably uninhibited buoyancy. With surface dewpoints in the upper 60s to low 70s F, that heating should offset weak low/middle-level lapse rates enough to yield MLCAPE generally in the 1000-1500 J/kg range. With little change in either heights or height gradient aloft, mid/ upper-level winds and deep shear should remain favorable through the day, albeit with some decrease as winds veer near the surface. Supercell and bowing/clustered modes are possible within the band(s) of convection. However, the veering will lead to gradual shrinking/ straightening of hodographs during the period of daytime destabilization (offsetting factors). This will make tornado potential conditional on more storm- to local-scale effects. Activity should weaken with southward extent this evening as the combined boundary moves into a nocturnally stabilizing airmass, with still more veering of near-surface flow. ..Edwards/Dean.. 01/16/2024 Read more View the full article

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0330 AM CST Tue Jan 16 2024 Valid 191200Z - 241200Z ...DISCUSSION... The beginning of the period will see an upper trough over the eastern states and an upper ridge over the West. The upper ridge will weaken as it slides east over the Plains on Day 5/Sat, with a lower-amplitude pattern emerging east of the Rockies through Day 6/Sun. During the latter half of the period, an upper trough is forecast to develop over the western U.S. Strong surface high pressure over the Plains on Day 4/Fri will shift east through the period, and another frontal intrusion into the Gulf of Mexico will result in a generally dry/stable airmass for much of the Day 4-8 period. As the western upper trough develops late in the period, surface lee troughing will promote southerly low-level flow over the southern Plains and some Gulf moisture return is expected. As this occurs, thunderstorm potential may increase across parts of the southern Plains around Days 7-8/Mon-Tue. Modest deep-layer flow over the region, and the upper trough remaining well west, will likely limit severe potential until perhaps just beyond Day 8/Tue. Read more View the full article
