Tropical Depression Aletta Forecast Discussion Number 4

Issued at 200 AM MST Fri Jul 05 2024 000 WTPZ41 KNHC 050836 TCDEP1 Tropical Depression Aletta Discussion Number 4 NWS National Hurricane Center Miami FL EP012024 200 AM MST Fri Jul 05 2024 Data from the ASCAT-B and ASCAT-C scatterometers, which both provided a good sampling of Aletta's circulation, revealed that the system no longer had tropical-storm-force winds. The scatterometer data also showed that the center of the tropical cyclone is displaced to the west of the remaining area of deep convection, presumably due to easterly vertical wind shear. Accordingly, the system is being downgraded to a tropical depression on this advisory. During the next day or two, Aletta should be under the influence of increasingly dry air with continued moderate shear, while moving over marginal sea surface temperatures. Therefore the system is expected to degenerate into a remnant low in 12 to 24 hours, and dissipate soon thereafter. This is similar to the previous official intensity forecast. Aletta is turning to the left with an initial motion estimate of 290/10 kt. The weakening cyclone should turn westward to west-southwestward within the low-level flow until dissipation.

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0239 AM CDT Fri Jul 05 2024 Valid 071200Z - 081200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF CENTRAL KANSAS INTO OKLAHOMA... ...SUMMARY... Severe storms are expected in parts of the central and southern Plains on Sunday. Some tornado risk will exist as tropical cyclone Beryl approaches the lower Texas Gulf Coast. ...Synopsis... A broad upper trough will be situated across much of the central CONUS into parts of the Midwest and Northeast. A shortwave perturbation within the flow will move southeastward out of Colorado into parts of Kansas and Oklahoma. At the surface, models are in agreement that a surface low will deepen in the southern High Plains. Rich moisture will return northward into Oklahoma and parts of at least southern Kansas. The exact position of the triple point and weak warm front/theta-e boundary is not certain and there is at least some potential for the boundary to be modulated by decaying early morning convection. ...Kansas/Oklahoma/North Texas... Some convection is likely to be ongoing at the start of the period in parts of Kansas to potentially northern Oklahoma. Some amount of diurnal weakening of this thunderstorm activity is possible. By the afternoon, heating of the moist airmass (upper 60s to low 70s F dewpoints) will promote the development of strong buoyancy (2000-3000 J/kg MLCAPE). The primary uncertainty at this juncture is how far north will convection begin to intensify. The ECMWF/GFS reintensify convection in parts of central Kansas with the NAM developing stronger convection along outflow from decaying morning convection in northern Oklahoma. With moderately strong northwesterly flow at mid-levels, effective shear of 40-50 kts can be expected. Given the potential for a severe wind producing MCS, 15% severe probabilities have been added to parts of these areas. ...South Texas... Per the latest NHC forecast, TC Beryl is expected to be near the lower Texas Gulf Coast late Sunday into Monday morning. With dewpoints in the 70s F being advected onshore and low-level shear strengthening in the northeast quadrant of the TC, some tornado risk is possible mainly Sunday night into Monday morning. ..Wendt.. 07/05/2024 Read more
