Near Term Update - Now Through Friday
A surface ridge of high pressure will build across the Mississippi Valley region and adjacent north central Gulf Coast region through the end of the week. A very dry airmass will remain entrenched across our forecast area through Friday with precipitable water values remaining near or just below 0.5 inches. Mostly clear and dry conditions can be expected through Friday.

High temperatures today will range in the mid to upper 70s across the majority of the region today and perhaps up to around 80 degrees along a few coastal locations. We did adjust forecast dewpoints below NBM guidance numbers this afternoon as these dry post-frontal airmasses tend to mix dewpoints lower than expected. Northerly winds will remain elevated between 10-15 mph with higher gusts at times across the region today. Another very cool night is expected tonight as winds relax across the area with clear skies. Expect low temperatures to tank into the low 50s across inland communities with upper 50s to right around 60° at the beaches by Friday morning. High pressure continues to build into the region Friday and temperatures will trend warmer with highs in the upper 70s to around 80°. The rip current risk will remain low. 07/21

Short Term - Friday Night Through Saturday Night
Can we just go ahead and save this weather for the remainder of the year and maybe into next year as this weekend will be near perfect. Dry northwesterly flow will continue through the period on the backside of a deep upper level trough centered over the eastern US. A weak reinforcing shortwave will likely pivot around the trough bringing a reinforcing shot of drier air to the area Friday night into Saturday. This will lead to dry and mild conditions through the weekend. With dewpoints in the low 50s, low temperatures will range in the low to mid 50s across the area on Friday night. Highs on Saturday will probably warm up quite nicely despite the cool start as drier air will allow for quick radiational heating and lack of cloud cover leading to better insolation. Highs on Saturday will likely climb into the low to mid 80s with maybe a few locations hovering in the upper 70s. By Saturday, lows will slowly begin to increase as the cold air begins to become modified by the warmer gulf waters and mixing throughout the day. Lows on Saturday night will range from around 60 along the coast to mid 50s inland.

.EXTENDED TERM /Sunday Through Wednesday/...Dry conditions will continue to prevail on Sunday and Monday as a surface high pressure remains positioned over the Southeast. By Tuesday and Wednesday, models are coming back into agreement that an upper-level ridge will build over the central CONUS. Additionally, surface winds are forecast to shift from a drier northeasterly flow to a more modified southeasterly flow. In response to this, dew points are expected to gradually rise from the upper 50s/lower 60s on Sunday to the upper 60s/near 70 by Wednesday. This increase in moisture will give way to a slight chance of Probability of Precipitation for much of the area on Wednesday, with slightly higher probabilities in our southern Mississippi counties. High temperatures throughout the extended will generally be in the mid to upper 80s. /96

Marine
A Small Craft Advisory remains in effect for much of the marine area until 10am CDT this morning. Small Craft Exercise Caution headlines will likely be needed for the open Gulf waters this afternoon through Friday morning as offshore flow remains elevated. Winds otherwise diminish into this weekend. /21.
