After 11z ifr cigs and MVFR vsbys wl be possible at the cntrl and south ms taf sites. Conditions will improve toVFR areawide by 16z and prevail Thursday aftn away from scattered tsra. 22 Discussion Tonight and Thursday: the convection currently ongoing this afternoon across portions of the area will diminish later this evening, with dry weather expected overnight. Lows tonight will generally be in the lower to middle 70s. Patchy fog will be possible towards morning mainly for areas that received rainfall. For Thursday, southerly moist flow will continue to increase moisture across the area, with pwats climbing above 2.0 inches over most of the area. Scattered to numerous showers and thunderstorms are likely with high temperatures around 90 degrees. With the better coverage of showers and storms expected Thursday, heat index values should remain below criteria for any mention of heat stress in the hwo. 27 Friday through Tuesday: while there is some trough ridge movement in the northern half of the us, the pattern remains consistent over our region. A ridge continues to hold over the southern us, fostering weak onshore flow which is bringing in ample moisture from the gulf of mexico. Two inch pws will remain socked in to the |
region throughout the weekend. While this moisture will keep conditions humid, it also means more cloud cover and more rainfall and, therefore, temperatures will also be slightly "cooler" for the end of august. Normal high temperatures for this time of year are around 92f. Highs this weekend will be between 88f-91f. Widespread afternoon convection is expected daily. With this convection and with these kinds of pws in place, any shower will be capable of producing some very efficient rainfall. Flash flooding is not expected due to the peak of growing season but areas that consistently see heavy rainfall each day may see some isolated flooding. By Sunday, some slight troughing will begin to affect the area... Though to the untrained eye, there will be no changes to the weather. Conditions will still be hot and humid with afternoon showers. As the shortwave trough shifts east of the area by Tuesday, rain chances will finally drop a bit.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
