SIOUX FALLS, S.D. (Dakota News Now) -- The weather so far for the 4th of July holiday weekend has been good with plenty of sunshine and temperatures in the 90s. Winds came up a bit along with humidity levels for our Saturday. Heat and humidity levels will come up a little more for some for the 4th itself, which has prompted heat alerts for parts of the Dakota News Now area.

4TH OF JULY: It’ll be another hot and mostly dry day along with higher humidity levels. That has prompted a HEAT ADVISORY to be issued for parts of the area from noon until 8 PM. We’ll see a mostly sunny to partly cloudy sky, but there is a chance of some pop-up showers and thunderstorms late in the afternoon through the evening hours. There is a marginal risk of isolated strong to severe thunderstorms southeast of a line from Watertown to Winner. Winds will be breezy out of the S and SW once again, but will shift to the N and NNW as a cold front moves in from the northwest. Highs will climb into the mid 90s to low to mid 100s. Dewpoints will be in the 60s, so expect the feels like temperature to be a couple degrees higher than the actual air temperature. Lows fall back into the 60s to near 70.

MONDAY: Another hot and muggy day is expected with a mostly sunny to partly cloudy. Clouds will increase slowly from west to east in the afternoon along with increasing chances of showers and thunderstorms. Chances will begin in the afternoon along and west of the Missouri, but gradually increase in coverage Monday night. Winds will be out of the N and E at 5-15 mph. Highs top out in the 90s with lows in the 60s and low 70s.

TUESDAY: Showers and thunderstorms will be likely as a low pressure system tracks across the area. Most areas should pick up 0.10-0.50″ of rain with some higher amounts in spots. Highs will cool back into the 70s and 80s, so a little below average.

WEDNESDAY AND BEYOND: Clouds will linger a bit on Wednesday with a little more sunshine by Thursday. A warm front will bring a boost in temperatures for areas in central and western South Dakota. Showers and thunderstorms are possible for the eastern half of the area Thursday night into Friday morning. Next weekend as of now looks great with sunshine and temperatures near to slightly above average. Highs look to be in the 70s and 80s Wednesday, 80s and 90s Thursday with some areas west pushing triple digits. After that, highs look to settle back into the 85-90 degree range.
