SUMMARY OF 300 AM MDT...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...28.3N 111.5W ABOUT 40 MI...70 KM WNW OF GUAYMAS MEXICO MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...N OR 350 DEGREES AT 10 MPH...17 KM/H MINIMUM CENTRAL PRESSURE...1005 MB...29.68 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The government of Mexico has discontinued the Tropical Storm warning for western mainland Mexico. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 300 AM MDT (0900 UTC), the center of Tropical Depression Lorena was located near latitude 28.3 North, longitude 111.5 West. The depression is moving toward the north near 10 mph (17 km/h), and this general motion is expected to continue during the next 12 to 24 hours. On the forecast track, the center of Lorena is expected to cross the coast of mainland Mexico during the next few hours, followed by a motion across northwestern Mexico. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Little change in strength is likely before landfall. After landfall, Lorena is expected to rapidly weaken, and the system is forecast to dissipate over northwestern Mexico later today. The estimated minimum central pressure is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Lorena can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC and on the web at www.hurricanes.gov/text/MIATCDEP5.shtml. RAINFALL: Lorena is expected to produce total rain accumulations of 3 to 6 inches over central Sonora, and additional rainfall of less than one inch over Baja California Sur through today. This rainfall may result in life-threatening flash floods in Sonora. SURF: Swells generated by Lorena will continue to affect portions of the western coast of Mexico today before subsiding on Monday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

The initial intensity is reduced to 30 kt based on ASCAT data. With no models showing any significant re-development of deep convection, slow weakening is forecast, and the cyclone should decay into a remnant low later today. The new intensity forecast is basically an update of the previous one, adjusted for lower initial winds. Mario is now moving a little faster with an initial motion of 335/8 kt. The track guidance is in good agreement on a north- northwestward at a slower pace through 48 hours. The new forecast track is very close to the previous one and the latest consensus aids.

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0348 AM CDT Sun Sep 22 2019 Valid 251200Z - 301200Z ...DISCUSSION... Models are in relatively good agreement with the large-scale pattern through the D8 period, indicating at least isolated severe storm potential each day. On Wednesday/D4, a strong shortwave trough will move east from the upper MS Valley across the Great Lakes, with a cold front becoming east-west oriented as it approaches the OH Valley. This front will extend westward into MO, KS, and OK, with a moist and unstable air mass to the south. Lift with the upper trough will continue to move away from the frontal zone, but at least isolated severe storms will be possible due to heating and low-level convergence. Predictability is low in part due to potential for ongoing early-day storms. For the D5-D6 time frame, the upper low over the Southwest is expected to move across the Plains, and will aid lift and increase shear. Moisture will be in place, with a conditional threat of a few severe storms over the central Plains, but timing of this small feature is uncertain. Beyond D6, the pattern becomes quite amplified, with a large scale trough developing over the West, and an upper ridge over the East. This will result in strong southwest flow aloft over the Rockies and High Plains, while southerly surface winds maintain low-level moisture across the Plains. Lift from warm advection could potentially support a few severe storms over the northern Plains Saturday/D7 and Sunday/D8 night. Read more

5 years 11 months ago
SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0230 AM CDT Sun Sep 22 2019 Valid 241200Z - 251200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF IOWA...WESTERN WISCONSIN...AND SOUTHERN MINNESOTA... ...SUMMARY... Severe storms are possible Tuesday across much of Iowa, Wisconsin, and southern Minnesota, with isolated storms from parts of the central Plains to the Upper Great Lakes. ...Synopsis... An elongated upper jet will dive southeastward across the northern Plains and into the upper MS Valley on Tuesday, with significant cooling aloft and increasing shear. The strongest lift will focus over MN, IA and WI as a cold front collides with returning low-level moisture with at least mid 60s F dewpoints. The cold front will progress eastward toward northern IL by Wed morning, while western parts of the front stall from KS into the TX Panhandle. To the west, an upper low will continue southward across western AZ and into the northern Baja, maintaining a favorable environment for scattered storms over southern AZ and NM. ...Upper MS Valley to the central Plains... Most of the area will remain free of thunderstorms for much of the day as the moist plume becomes established and temperatures aloft cool. By around 00Z, storms are expected to form along the front from southern MN into IA and perhaps eastern NE, and will expand in coverage through the evening into WI. Strong deep-layer shear perpendicular to the front will favor supercells, with steep lapse rates aloft and around 200 m2/s2 ESRH favoring very large hail and perhaps a tornado or two. Farther south into KS, strong heating of a 65-70 F dewpoint air mass will lead to over 3000 J/kg MUCAPE, with isolated severe storms expected across central and eastern KS. Hail will be possible, with localized wind damage. Parts of this area may require a categorical upgrade in later outlooks once placement of potential storm clusters is more precise. ...Southern AZ and southwest NM... Scattered to numerous storms may be ongoing Tuesday morning over southern AZ and NM in association with the upper low. Pockets of destabilization may occur once again during the day, with isolated strong to severe storms possible capable of hail or localized wind damage. ..Jewell.. 09/22/2019 Read more

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0230 AM CDT Sun Sep 22 2019 Valid 241200Z - 251200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF IOWA...WESTERN WISCONSIN...AND SOUTHERN MINNESOTA... ...SUMMARY... Severe storms are possible Tuesday across much of Iowa, Wisconsin, and southern Minnesota, with isolated storms from parts of the central Plains to the Upper Great Lakes. ...Synopsis... An elongated upper jet will dive southeastward across the northern Plains and into the upper MS Valley on Tuesday, with significant cooling aloft and increasing shear. The strongest lift will focus over MN, IA and WI as a cold front collides with returning low-level moisture with at least mid 60s F dewpoints. The cold front will progress eastward toward northern IL by Wed morning, while western parts of the front stall from KS into the TX Panhandle. To the west, an upper low will continue southward across western AZ and into the northern Baja, maintaining a favorable environment for scattered storms over southern AZ and NM. ...Upper MS Valley to the central Plains... Most of the area will remain free of thunderstorms for much of the day as the moist plume becomes established and temperatures aloft cool. By around 00Z, storms are expected to form along the front from southern MN into IA and perhaps eastern NE, and will expand in coverage through the evening into WI. Strong deep-layer shear perpendicular to the front will favor supercells, with steep lapse rates aloft and around 200 m2/s2 ESRH favoring very large hail and perhaps a tornado or two. Farther south into KS, strong heating of a 65-70 F dewpoint air mass will lead to over 3000 J/kg MUCAPE, with isolated severe storms expected across central and eastern KS. Hail will be possible, with localized wind damage. Parts of this area may require a categorical upgrade in later outlooks once placement of potential storm clusters is more precise. ...Southern AZ and southwest NM... Scattered to numerous storms may be ongoing Tuesday morning over southern AZ and NM in association with the upper low. Pockets of destabilization may occur once again during the day, with isolated strong to severe storms possible capable of hail or localized wind damage. ..Jewell.. 09/22/2019 Read more
