WRUF Weather

Rain Chances Return by Week’s End

Our first fall-like cold front didn’t drop the temperature much, but it did drop the humidity enough to eliminate those afternoon showers and thunderstorms Floridians know all to well this time of year.  We’ve made it two days in a row without one drop of rain across North-Central Florida, a trend that will become more common as the rainy season comes to an end later in the fall.  However,the moisture didn’t move far.  Residents of central and southern Florida haven’t had the chance to enjoy the comfortable weather yet because the cold front ran out of gas near the I-4 corridor.  It won’t take long for the humidity to return, though, as a subtle shift in the winds are expected to open the door for it’s migration back to the north by week’s end.

The Set Up:  High pressure nosing down the east coast of the United States has delivered a northeast breeze and allowed the drier air to filter in over the past three days.  As the winds veer more to the east and eventually southeast, moisture will begin to drift north and northwestward.  With the return of the humidity will come the return of those typical afternoon showers as well.  Moisture will be first to move back on-shore near the Atlantic coast, where persistent easterly winds will transport a weak wave of lower pressure inland.  As a result, rain chances late Wednesday and Thursday will be highest east of the I-75 corridor.  A more southerly component to the wind will create an environment favorable for afternoon showers and thunderstorms across all of North-Central Florida over the weekend.

The Bottom Line

Rain showers will be spotty and brief for the next two days, mainly east of the I-75 corridor.  Chances for longer lasting and heavier showers or thunderstorms will be increasing Friday and through the weekend.
