An upper level shortwave trough will move across the viewing area during the morning hours, producing showers and thunderstorms. As the upper reaches further east toward the southern Appalachians, rain chances will increase in this higher elevation area east of Highway 75. The good news is that downslope motion in the wake of the trough should lead to a decrease in the rain and thunderstorms. coverage during the afternoon hours and an increase in sunshine. Increasing sunshine will push afternoon high temperatures into the lower 80s, and it could generate just enough instability for isolated thunderstorms to develop over the Cumberland Plateau from mid-afternoon to mid-evening.

We could enjoy a mostly sunny day on Monday as relatively drier and more stable air spreads eastward across the region. If a thunderstorm develops in the afternoon, it should be primarily anchored in the higher terrain on the plateau and over the higher peaks of the southern Appalachians. The extended period of sunshine and the southerly low will result in even warmer temperatures on Monday. Highs should reach the upper 80s. It looks like we will only see a slight increase in the chance of afternoon showers and thunderstorms on Tuesday as the local atmosphere becomes slightly more unstable. While there is a chance that some of these storms will push into the Tennessee Valley, most development will remain on higher ground. Temperatures will be above normal again on Tuesday, with highs possibly even a degree or two above Monday’s highs. Chattanooga could reach 90 degrees by late afternoon!

The heatwave should be tempered by increasing cloud cover and an increasing chance of showers and thunderstorms as we move from Wednesday to Thursday. The reason for the higher probabilities is that model forecasts show a synoptic cool front building southward across the News12 viewing area later Wednesday evening into Thursday. This boundary should generate a broad band of showers and thunderstorms during this period. The interesting thing about our mid-week weather pattern is that another relatively strong, cool front will follow behind this initial frontal advance. The second front will drop south through the Ohio Valley early Thursday, moving south into the Tennessee Valley and southern Appalachians Thursday evening through Friday. Model forecasts indicate that showers and thunderstorms will become likely again associated with this boundary.

News12 viewers will enjoy a return to mostly sunny skies Friday and Saturday as drier air builds southward across the southeastern U.S. The drier air will feel great after our mid-week period of high humidity. One aspect of ‘cold’ fronts during the warm seasonal months of June, July and August is that temperatures in the wake of these boundaries are usually even warmer. The reason warmer air “follows” cold fronts in summer is that the greater coverage of clouds and convective precipitation ahead of the front reduces high temperatures. This is what we could experience Wednesday, and possibly Thursday as well, as highs may remain limited to the mid 80s. With more sun expected Friday and Saturday, temperatures could be a degree or two higher. So highs on Friday and Saturday could end up in the upper 80s again, but with much lower humidity. As they say, “Don’t worry, it won’t be that bad; it is a dry heat”!

National drought overview for May 23, 2024

Southeast

Moderate to heavy precipitation accumulations have been observed in isolated areas of the region over the past week, including southern portions of Alabama and Georgia and in the Florida Panhandle, with precipitation totals ranging from 2 to 6+ inches. Elsewhere in the region, isolated showers were observed with accumulations ranging from 1 to 3 inches. Average temperatures during the week were generally above normal (2 to 8 degrees F), except in areas of south and central Alabama, as well as Georgia and the Carolinas. On the map, this week’s rainfall led to the disappearance of areas of abnormally dry areas (D0) in North Carolina and Virginia, while areas of South Florida saw continued decline with expansion of areas of moderate drought (D1) due to worsening drought-related conditions. during the last 90 day period.

According to the U.S. Army Corps of Engineers, Lake Okeechobee’s water level has been declining since late March; however, current levels are still near normal for the date compared to long-term averages (based on 1965-2007 averages).

According to the USDA (May 19), grazing and range conditions are rated good to excellent statewide: Virginia 63%, North Carolina 87%, South Carolina 82%, Georgia 65%, Alabama 82% and Florida 42%.

Who can participate?

This is a community project. Everyone can help, young, old and in between. The only requirements are an enthusiasm for viewing and reporting weather conditions and a desire to learn more about how weather can impact and influence our lives.

What will our volunteer observers do?

Every time a rain, hail or snow storm moves through your area, volunteers take precipitation measurements at as many locations as possible (see equipment). These precipitation reports are then recorded on our website www.cocorahs.org. The data is then displayed and organized so that many of our end users can analyze it and apply it to everyday situations, ranging from water resource analysis and severe storm warnings to neighbors comparing how much rain fell in their backyard.

Who uses CoCoRaHS?

CoCoRaHS is used by a wide variety of organizations and individuals. The National Weather Service, other meteorologists, hydrologists, emergency managers, city corporations (water supply, water conservation, stormwater), insurance adjusters, USDA, engineers, mosquito control, ranchers and farmers, outdoor and recreation advocacy groups, teachers, students, and neighbors in the community are just some examples of those who visit our website and use our data.
