Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0733 AM CDT Tue Sep 02 2025 Valid 021300Z - 031200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF THE UPPER MIDWEST... ...SUMMARY... Thunderstorms with potential for isolated severe wind gusts and marginally severe hail will be possible this afternoon into the early evening across parts of the Upper Midwest. ...Upper Midwest... An upper trough initially over central Canada will dig southeastward into the Upper Midwest/Lake Superior vicinity during the period. Showers and weak thunderstorms ongoing this morning over MN, aided by an MCV over northern MN, will gradually dissipate with differential heating/residual outflow arcing from southern MN west-northwestward towards the Dakotas/MN border by mid afternoon. A cold front initially over ND will advance southeastward into an adequately moist airmass, featuring surface dewpoints in the lower to mid 60s F ahead of it. Diurnal heating will likely yield moderate SBCAPE (1500-2000 J/kg) ahead of the front by mid-late afternoon. Model guidance is consistent in showing a band of scattered thunderstorms developing from the eastern half of SD into central MN by the mid-late afternoon. Upscale growth with higher storm coverage is expected from near the MN/SD border eastward into central and southern MN during the 22-02 UTC period. The stronger mid- and upper-level flow will likely lag behind the surface front and limit effective shear magnitudes (at or below 25 kt). However, a few organized multicells could be associated with isolated severe wind gusts and hail before this activity subsides during the early-mid evening. ..Smith/Bentley.. 09/02/2025 Read more

Tropical Depression Twelve-E Forecast Discussion Number 2

3 weeks 6 days ago
Issued at 200 AM MST Tue Sep 02 2025 256 WTPZ42 KNHC 020856 TCDEP2 Tropical Depression Twelve-E Discussion Number 2 NWS National Hurricane Center Miami FL EP122025 200 AM MST Tue Sep 02 2025 The tropical depression has been relatively steady overnight. Periodic bursts of deep convection continue to form over the low-level center, with cold cloud tops of less than -80 degrees C. A scatterometer pass from 0335 UTC showed a small circulation with reliable winds of 30 kt. The initial intensity is therefore held at 30 kt, which is also supported by the latest TAFB T2.0 classification. The cyclone is still moving west-northwestward at 13 kt along the southwestern periphery of a mid-level ridge. The ridge should soon begin to steer the depression generally northwestward for the next couple of days. By the end of the week, the tropical cyclone is expected to slow down as it reaches a weakness in the ridge and gradually turn northward. Over the weekend, the depression is forecast to turn north-northeastward to northeastward toward the Baja California peninsula. The latest official forecast track is west of the previous forecast as a result of an adjustment to the initial position reflecting a delay in the northwestward turn, and lies between the simple and corrected consensus aids. Warm waters and a quiescent, moist atmosphere should allow the depression to steadily intensify during the next couple of days. The system is still expected to peak just under hurricane strength. By day 3, the cyclone is forecast to cross the 26 degree C isotherm and experience increasing vertical wind shear and decreasing mid-level humidities which should cause gradual weakening. Little changes have been made to the latest intensity forecast. Interests in southwestern Mexico and Baja California Sur should monitor the progress of this system. A Tropical Storm Watch could be required for portions of Baja California later today or Wednesday.

Hurricane Kiko Forecast Discussion Number 9

3 weeks 6 days ago
Issued at 1100 PM HST Mon Sep 01 2025 000 WTPZ41 KNHC 020852 TCDEP1 Hurricane Kiko Discussion Number 9 NWS National Hurricane Center Miami FL EP112025 1100 PM HST Mon Sep 01 2025 The satellite presentation of Kiko has improved since the previous advisory, with what appears to be a developing inner-core and hints of an eye evident at times in infrared satellite images. The most recent subjective Dvorak current intensity estimates from TAFB and SAB were both 4.0/65 kt. The objective estimates from UW-CIMSS have ranged between 53 and 71 kt during the past several hours, and have been trending upwards. Therefore, the initial intensity for this advisory has been raised to 65 kt, making Kiko a category 1 hurricane. Kiko is moving due west, or 270 degrees, at 6 kt. This general motion is expected to continue during the next several days as the cyclone is steered by a building subtropical ridge to its north and northwest. A turn toward the west-northwest is forecast by days 4 and 5 as an upper-level trough north of Hawaii begins to erode the western portion of the subtropical ridge. It should be noted that there remains considerable along-track spread among the global models, although the GFS and ECMWF day 5 positions have come into much better agreement since the previous model cycle. The official track forecast remains in good agreement with the latest multi-model consensus aids and is very close to the previous advisory through 60 hours, then slightly to the north of the previous track forecast from day 3 onward. Kiko will remain over warm waters of 27–28C and influenced by mostly light vertical wind shear through day 4. The surrounding environmental mid-level moisture appears to be a somewhat limiting factor for significant intensification, however, remaining between 50 and 60 percent through day 3, then trending below 50 percent by days 4 and 5. The latest intensity guidance has trended significantly higher from the previous model cycle, and the official forecast reflects this change and has been nudged upward accordingly. The official intensity forecast remains on the higher end of the intensity guidance, and is most closely aligned with the FSSE intensity consensus aid.

3 weeks 6 days ago
Issued at 200 AM MST Tue Sep 02 2025 089 WTPZ32 KNHC 020849 TCPEP2 BULLETIN Tropical Depression Twelve-E Advisory Number 2 NWS National Hurricane Center Miami FL EP122025 200 AM MST Tue Sep 02 2025 ...TROPICAL DEPRESSION FORECAST TO STRENGTHEN LATER TODAY... SUMMARY OF 200 AM MST...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...17.6N 106.8W ABOUT 190 MI...305 KM WSW OF MANZANILLO MEXICO MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...WNW OR 290 DEGREES AT 15 MPH...24 KM/H MINIMUM CENTRAL PRESSURE...1007 MB...29.74 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. Interests in southwestern Mexico and Baja California Sur should monitor the progress of this system. A Tropical Storm Watch could be required for portions of Baja California Sur later today or on Wednesday. DISCUSSION AND OUTLOOK ---------------------- At 200 AM MST (0900 UTC), the center of Tropical Depression Twelve-E was located near latitude 17.6 North, longitude 106.8 West. The depression is moving toward the west-northwest near 15 mph (24 km/h), and a gradual turn toward the northwest and north-northwest with a decrease in forward speed is expected over the next couple of days. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Strengthening is forecast, and the system will likely become a tropical storm later today. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Areas of heavy rainfall well east and northeast of the depression will continue to impact portions of northwestern Mexico from the states of Colima to Sinaloa today, with isolated flash flooding possible in areas of mountainous terrain. Bands of heavy rainfall are expected to begin impacting Baja California Sur by Wednesday and potentially persist through Saturday, with rainfall totals of 4 to 8 inches possible across portions of the area. Uncertainty remains with these totals, and locally higher or lower amounts are possible depending on the track and strength of the system. Potentially significant flash flooding is a possibility. NEXT ADVISORY ------------- Next complete advisory at 800 AM MST. $$ Forecaster Bucci
