Looking at current surface analysis, surface high pressure currently centered off the South Carolina coastline has continued to suppress any cloud cover across Central Alabama today, and drier are has mixed down to the surface from the mid levels of the atmosphere. Temperatures climbed into the lower 90s across our area today and hot conditions will look to persist into the foreseeable future. Upper level high pressure will begin to dominate the eastern part of the Southeast early in the week.
Models are consistent with the upper high currently contered over western North Carolina to move northward into eastern Kentucky and western Virginia on Monday. The high then elongates south and westward by Tuesday morning, in response to a trough trying to move eastward into the upper high. The placement of the high will actually allow a weak easterly flow to set up across the Southeast and Atlantic moisture will allow the chance of showers and thunderstorms on Wednesday and Thursday afternoon.
Upper high pressure remains in control through the rest of the week with hot temperatures persisting through the remainder of the period. Most locations should reach into the mid 90s by Thursday afternoon with possibly upper 90s in a few spots with only isolated showers and thunderstorms possible during the peak heating of the day.
