Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1141 AM CDT Fri Jul 05 2024 Valid 051630Z - 061200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE MIDDLE OHIO VALLEY AND CENTRAL APPALACHIANS VICINITY... ...SUMMARY... Scattered severe thunderstorms will be possible through early evening across parts of the middle/upper Ohio Valley to the Appalachians. Isolated damaging wind gusts (50-65 mph) will be the primary severe hazard. ...Lower Great Lakes/Ohio Valley/Appalachians... Bands of linear strong-to severe storms continue to organize and modestly intensify at midday across the Cumberland Plateau northward toward the Ohio River/far southern Ohio near a surface boundary, although cirrus/cloud debris is more prevalent with northward extent. In the presence of 1500-2500 J/kg MLCAPE and modest-strength westerlies, the main potential for damaging winds through early evening should focus from eastern Kentucky into West Virginia and far western Virginia, and possibly also east/northeast Tennessee. Farther north, more uncertainty and potentially lower strong/severe storm coverage will extend from Lower Michigan across the southern/Lower Great Lakes into Pennsylvania and New York. A hail threat may also exist across parts of Lower Michigan, ahead of the upper-level trough, where mid-level temperatures will be cooler with steeper mid-level lapse rates. Even so, localized damaging gusts will be the main severe risk overall. ...Eastern New Mexico... The region will be on the southern periphery of stronger northwesterly flow aloft. Strong heating and moist low-level upslope flow (dewpoints near 60 F) will contribute to initially isolated storms preferentially developing over the higher terrain by early to mid-afternoon. Model guidance shows MLCAPE peaking in the 1500-2000 J/kg range, with 0-6 km shear around 30 kt. Some organization of storms is possible, mainly via multicells and perhaps a few supercell structures. Isolated severe gusts/hail may accompany the stronger thunderstorms. ...Montana... A southeastward-moving low-amplitude shortwave trough over southern Alberta will continue southeastward over northern/eastern Montana, and toward the adjacent northern High Plains by tonight. Ample heating and 40s/lower 50s F surface dewpoints will contribute to 500-1000 J/kg MLCAPE across north-central/eastern Montana. A few strong to locally severe storms may be capable of hail and locally severe wind gusts for a few hours late this afternoon and early evening, before storm intensity subsides later in the evening. ..Guyer/Karstens.. 07/05/2024 Read more

Drought ruined much of North Carolina's corn

1 year 2 months ago
Much of North Carolina’s corn appeared to be a total loss, according to agronomists. The overall condition of the crop was “very, very poor,” as described by a regional agronomist for the North Carolina Department of Agriculture. Although the first cutting of hay was great, there has been little rainfall since then, so a second cutting was not looking promising. In addition, pasture conditions were very poor statewide. Some growers were already feeding freshly cut hay to their livestock, which could lead to a hay shortage this coming winter. Soybeans, tobacco, peanuts, and cotton were all suffering in the hot, dry weather, but could still benefit from rain. SF|Successful Farming (Des Moines, Iowa), June 28, 2024

Tropical Depression Aletta Forecast Discussion Number 5

1 year 2 months ago
Issued at 800 AM MST Fri Jul 05 2024 000 WTPZ41 KNHC 051442 TCDEP1 Tropical Depression Aletta Discussion Number 5 NWS National Hurricane Center Miami FL EP012024 800 AM MST Fri Jul 05 2024 Multiple microwave images between 08 and 12 UTC indicated that Aletta still has a well-defined center, and it has continued to produce a small area of deep convection near that center. Objective and subjective intensity estimates range from around 25 to 35 kt, so the estimated maximum winds are still 30 kt for this advisory. Aletta is moving westward (270/10kt) and a west-southwestward turn is expected later this morning. The small depression is located in a marginal environment, and a combination of decreasing SSTs below 26 deg C, drier surrounding air, and increasing shear should cause Aletta to lose its deep convection later today. In fact, all dynamical guidance suggests that Aletta will become a remnant low within the next 6 to 18 h. The NHC forecast conservatively maintains Aletta as a tropical cyclone on the longer side of that range, but still shows gradual weakening through the forecast period. After it becomes a remnant low, Aletta is expected to turn back toward the west and dissipate within another day or so.
