Meridian Regional Airport hit 101 degrees Monday afternoon. That's the third time we've hit at least 100 degrees this year, and it the hottest we have been in four years. We did not quite reach the record high of 102, which was set in 1980 and happened again 1990.
Mid-to-upper 90s the rest of this week will be only small relief. Heat indices will still be around 100-105 each afternoon through at least Friday. Locally higher temperatures, and thus heat indices, are possible in spots. In the heat of the afternoons, an isolated shower or two can form. Showers, however, are unlikely through Saturday.
Remember to stay hydrated by drinking plenty of water and eat well so your body is better able to handle the extreme heat. That's especially important if you will be spending a lot of time outside. In that case, you will also need to make sure you are taking cool breaks out of the heat to be safe.
When can we expect this heat to break? A surge of moisture off of the Gulf of Mexico ahead of an approaching cold front will help to increase scattered showers and thunderstorms on Sunday and Monday. That will help immensely, but temperatures will likely still be above the normal high of 89 degrees. "Normal" is the average of thirty years. Long range forecasts indicate more above-normal temperatures for at least the next two weeks.
