marginally favorable for slow development of this system as it
moves slowly eastward to the south of the coast of Mexico through
the middle of this week.
* Formation chance through 48 hours...low...10 percent.

Isolated strong to severe thunderstorms are possible from the Ozarks into parts of the Tennessee and lower Ohio Valleys. ...Ozarks to TN/OH Valley Region... Northern-stream short-wave trough is forecast to dig into the northern Plains later this afternoon, which will encourage the positive-tilt trough over the central Plains to eject east, and deamplify over the MS Valley late in the period. This evolution is expected to aid weak surface wave/low development along the synoptic front, mostly likely over northern AR early in the period. Latest model guidance suggests this weak feature will track northeast into southern IN by 24/12z. While the surface front is not particularly sharp, this boundary will serve as the focus for scattered convection through the period. Pre frontal boundary-layer heating will prove instrumental in destabilization as mid-level lapse rates should remain weak through the period. Latest NAM suggests 0-3km lapse rates will steepen across eastern AR into western KY by early afternoon, which will result in MLCAPE in excess of 1000 J/kg, coincident with modest 0-6km bulk shear. Forecast soundings favor multi cell updrafts with some organizational potential, as effective shear will be on the order of 30kt along this pre frontal corridor. At this time it appears most updrafts will struggle to generate more than marginally strong gusts, or perhaps some hail approaching 1 inch. Most robust updrafts should develop by late morning and continue into the early-evening hours before nocturnal cooling lessens buoyancy. ..Darrow/Thornton.. 09/23/2024 Read more

A Tipp City golf course has not had to mow the greens everyday or cut the fairways three times per week as drought has slowed grass growth, which has saved money on labor. WKEF-TV NBC 22 Dayton (Ohio), Sept 22, 2024

Some local reservoirs were below seasonal averages, prompting officials in the city of Columbus to begin using supplemental water from a reserve source. Columbus was in the watch phase of its drought management plan. No voluntary or mandatory water restrictions were in effect, but could be enacted if needed.

Issued at 900 PM CST Sun Sep 22 2024 000 WTPZ45 KNHC 230233 TCDEP5 Tropical Depression Ten-E Discussion Number 2 NWS National Hurricane Center Miami FL EP102024 900 PM CST Sun Sep 22 2024 Satellite images show that the depression is gradually becoming better organized, with some convective banding features developing around the circulation and a small area of very cold cloud tops over the estimated center. Upper-level outflow is fairly well defined over the southern semicircle of the system. Subjective Dvorak classifications from both TAFB and SAB indicate a T-number of 2.0, so the advisory intensity is held at 30 kt for now. Center fixes indicate little movement since earlier today, so the initial motion estimate is nearly stationary. As noted earlier, the track forecast for this tropical cyclone is quite problematic, with a large spread in the guidance models. The regional hurricane models are generally east of the global guidance, with the ECMWF on the western side of the model tracks. The most recent run of the GFS takes the cyclone inland in a couple of days but later develops one or two new centers offshore. Since the dominant steering mechanism seems to be the Central American Gyre, the official track forecast shows a mainly east-northeastward motion during the forecast period, along the southern periphery of the Gyre. This track moves the center close to the southern coast of Mexico for several days before making landfall, and lies between the simple and corrected dynamical model consensus predictions. During most of the forecast period, the system should remain over very warm waters with low vertical wind shear and in a moist low- to mid-level air mass. Therefore strengthening is likely, and the official intensity forecast is similar to the statistical-dynamical LGEM guidance. One major source of uncertainty in the forecast is how much the system interacts with land during the next few days. Given the favorable environment, it is possible that the system could become a hurricane before landfall. Interests along the coast of southern Mexico should closely monitor the latest forecast updates for this system. A Hurricane Watch could be required for a portion of the coast now covered by a Tropical Storm Watch. KEY MESSAGES: 1. Slow-moving Tropical Depression Ten-E will bring very heavy rainfall to coastal portions of southwest Mexico through the upcoming week. This heavy rainfall will likely cause significant and possibly catastrophic, life-threatening flash flooding and mudslides to the Mexican States of Chiapas, Oaxaca, and southeast Guerrero, particularly in areas near the coast. 2. The depression is forecast to become a tropical storm later tonight or on Monday. A Tropical Storm Watch is in effect for a portion of the coastline of southern Mexico, where tropical storm conditions could begin on Tuesday. 3. The system could strengthen more than forecast depending on how long it remains over water. Interests along the coast of southern Mexico should monitor the latest forecast updates, as a Hurricane Watch could be required for a portion of the coastline later tonight or on Monday.

DISCUSSION AND OUTLOOK ---------------------- At 900 PM CST (0300 UTC), the center of Tropical Depression Ten-E was located near latitude 13.9 North, longitude 98.6 West. The depression is nearly stationary, but a slow northeastward motion is expected later tonight and Monday. A northeastward to east-northeastward motion is anticipated on Tuesday and Wednesday. On the forecast track, the center of the system is forecast to move near the southern coast of Mexico during the next couple of days. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Strengthening is forecast during the next couple of days, and the system will likely become a tropical storm tonight or early Monday. The estimated minimum central pressure is 1003 mb (29.62 inches). HAZARDS AFFECTING LAND ---------------------- Key Messages for the depression can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC and on the web at hurricanes.gov/text/MIATCDEP5.shtml RAINFALL: Through Thursday, the Tropical Depression is expected to produce 6 to 12 inches of rain with isolated totals around 15 inches across the coastal areas of Chiapas. In areas along and near the Oaxaca coast to southeast Guerrero, between 10 and 20 inches of rain with isolated totals near 30 inches can be expected through Thursday. For a complete depiction of forecast rainfall associated with Tropical Depression Ten, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_ep10.shtml?rainqpf WIND: Tropical storm conditions are possible within portions of the watch area beginning on Tuesday. SURF: Swells associated with the depression are forecast to begin to affect the coast of southern Mexico on Monday, with the potential for dangerous surf and rip currents much of the week.
