Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1228 AM CDT Sun Sep 22 2019 Valid 231200Z - 241200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER MUCH OF CENTRAL AND SOUTHERN ARIZONA... ...SUMMARY... Scattered storms, some severe with damaging wind and hail, are expected over much of Arizona Monday. ...Arizona... An upper low will drop south from NV toward the lower Colorado River Valley, providing large-scale lift as well as increasing shear profiles. At the surface, southern winds will persist over southeast CA into southern AZ ahead of the developing cold front. Heating as well as gulf moisture with 60s F dewpoints will result in MLCAPE on the order of 1000-1500 J/kg with little if any capping. Severe storms, including damaging wind gusts and hail, will develop during the afternoon over southern and central AZ, and possibly extreme eastern CA and southern NV where heating will be maximized. Low-level winds will be generally weak, but beneath increasing southwesterlies aloft. This will elongate hodographs, which will be mainly straight-line, supporting splitting cells capable of hail. Some cells may bow and produce damaging winds as well. Sporadic strong to severe storms will be possible late into the night over southern AZ as the air mass remains unstable prior to the cold front passage. ...Northeastern states... A potent shortwave trough will move rapidly east from the Great Lakes into the Northeast, providing increasing deep-layer shear as well as lift. At the surface, a narrow plume of low 60s F dewpoints will spread northward ahead of a cold front which will move across NY and PA during the day, and across New England overnight. Despite increasing wind fields, instability is forecast to be weak, averaging just a few hundred J/kg, and with poor deep-layer lapse rates. This should result in primarily non-severe storms along the cold front, capable of a few strong wind gusts as low-level mean winds average around 35 kt. ...MAXIMUM RISK BY HAZARD... Tornado: 2% - Marginal Wind: 15% - Slight Hail: 15% - Slight ..Jewell.. 09/22/2019 Read more

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 657 NWS Storm Prediction Center Norman OK 510 PM CDT Sat Sep 21 2019 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southwest to northeast Kansas Southeast Nebraska * Effective this Saturday afternoon from 510 PM until Midnight CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph possible Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible A tornado or two possible SUMMARY...Scattered thunderstorms will develop this evening from southwest Kansas into southeast Nebraska with primary threats of large hail and damaging wind. This activity should evolve into one or more clusters with the severe threat waning towards late evening as it transitions to predominantly a heavy rainfall hazard. The severe thunderstorm watch area is approximately along and 70 statute miles east and west of a line from 35 miles northeast of Beatrice NE to 10 miles east southeast of Dodge City KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches.

Tropical Storm Mario Forecast Discussion Number 19

5 years 11 months ago
Issued at 900 PM MDT Sat Sep 21 2019 000 WTPZ44 KNHC 220254 TCDEP4 Tropical Storm Mario Discussion Number 19 NWS National Hurricane Center Miami FL EP142019 900 PM MDT Sat Sep 21 2019 Mario has been a swirl of low clouds devoid of convection since the last advisory. The initial intensity is reduced to 35 kt based mainly on subjective satellite intensity estimates from TAFB and SAB, and passive microwave winds from the WindSat suggests the possibility this is a bit generous. While Mario remains in an area of strong easterly vertical shear, it is still over warm sea surface temperatures and in a relatively moist air mass. Thus, the lack of convection is a little surprising. The intensity forecast will show little change in strength during the next 12 h in anticipation of a convective burst developing near the center during the diurnal maximum. After that time, dry air entrainment and movement over cooler waters should inhibit the development of convection, and the cyclone is forecast to decay into a remnant low by 36 h, if not sooner. The new intensity forecast is again mainly an update of the previous forecast. Mario is now moving a little faster with an initial motion of 350/6 kt. The track guidance is in good agreement on a north- northwestward to northwestward motion through about 48 h, followed by a more northward motion near the 72 h point. Once again, little change was made to the forecast track.

Tropical Storm Kiko Forecast Discussion Number 39

5 years 11 months ago
Issued at 500 PM HST Sat Sep 21 2019 000 WTPZ43 KNHC 220241 TCDEP3 Tropical Storm Kiko Discussion Number 39 NWS National Hurricane Center Miami FL EP132019 500 PM HST Sat Sep 21 2019 Kiko is only producing a relatively small patch of deep convection to the northeast of its center, the result of continued southwesterly shear and the cyclone moving through what appears to be a stable environment. The initial intensity is held at 45 kt based on the earlier ASCAT data, but it's possible the maximum winds have decreased since then. Given Kiko's structure and its environment, some weakening is expected during the next day or so. However, the cyclone is moving southwestward, toward slightly warmer waters, and this could allow for some restrengthening in 36-48 hours, which is shown by many of the intensity models. Another round of shear and cooler waters should lead to weakening after 48 hours, and Kiko is expected to degenerate into a remnant low by day 5, if not sooner. Kiko is moving a little faster toward the west-southwest, or 240/7 kt. An elongated mid- to upper-level trough extending from California to near the Hawaiian Islands is digging southward, which is forcing the subtropical ridge--and Kiko--to lose latitude during the next 36 hours. After that time, the western portion of the trough is forecast to cut off east of the Hawaiian Islands, causing Kiko to turn sharply northwestward on days 2-4. Once a remnant low, Kiko is then expected to be steered by lower-level flow, causing it to turn back to the southwest. Only small adjustments to the NHC track forecast were made on this cycle, and it still depicts a wave-like trajectory through day 5, as has been the case for several days.

Tropical Storm Lorena Forecast Discussion Number 19

5 years 11 months ago
Issued at 900 PM MDT Sat Sep 21 2019 000 WTPZ45 KNHC 220236 TCDEP5 Tropical Storm Lorena Discussion Number 19 NWS National Hurricane Center Miami FL EP152019 900 PM MDT Sat Sep 21 2019 Recent SSMI/S and WindSat microwave overpasses helped locate the center of Lorena, which was hidden under a band of cirrus clouds, over the Gulf of California southwest of Guymas. The system was devoid of convection for several hours. However, a new burst of convection has recently formed just northeast of the center. There is little data near the central core, so the initial intensity is set at 40 kt based mainly on continuity from the previous advisory. Lorena should make landfall over northwestern Mexico during the next several hours, then rapidly weaken over the mountainous terrain and dissipate over northwestern Mexico by Monday morning. The microwave data indicate that Lorena is continuing to move just west of due north or 355/10 kt. A general northward or perhaps north-northwestward motion is expected until the cyclone dissipates, and the new forecast track is changed little from the previous advisory track. Key Messages: 1. Lorena may produce dangerous flash flooding in Sonora Saturday night and Sunday. Moisture associated with Lorena may also result in locally heavy rain over parts of Arizona early in the week. There is a Slight Risk of excessive rainfall over central Arizona on Monday. 2. Lorena is expected to bring tropical-storm-force winds over portions of the tropical storm warning area during the next several hours.
