    The northwest flow pattern is expected to persist through the weekend, and the models are in decent agreement that another shortwave trough will push through the region on Saturday. In advance of this trough, high pressure will continue to dominate on Friday with clear skies and slightly below normal temperatures.
    Saturday night should continue to see mostly clear skies and dry conditions persist as surface winds remain out of the northeast, and fully expect to see lows cool back into the 30s north of I-10 and the lower 40s south of I-10.

    Due to the lack of strong moisture advection into the region on Saturday, only an increase in cloud cover is currently expected through the day.
    A Gulf low should begin to form over the north-central Gulf by Saturday night, and this may allow for coastal showers to begin developing by late Saturday and Sunday. However, the majority of the precipitation with this system will remain over the coastal waters and further into the central Gulf. So NO Snow for the Inland areas.
    By Sunday afternoon, strong subsidence and dry air advection will lead to clearing skies across most of South Mississippi. Temperatures will generally remain near average through the weekend with highs mid 50’s and lows in the low 30’s north in the Pine Belt to mid and upper 30’s near the Coast.
    The northwest flow pattern will begin to break down by next Monday and expect to see a more zonal flow pattern take hold. A surface high will remain in control of the area and expect to see dry weather and near average temperatures continue.

    However, both the GFS and the Euro indicate that another shortwave trough will begin to dive down from the northern Plains Monday night into Tuesday. This system should push another cold front through the area, and expect to see increasing cloud cover and rain chances on Tuesday with this frontal passage.
