SYNOPSIS AND OUTLOOK:
The upper-level trough to our east and weak upper-low over East Texas will shift east while high pressure aloft builds in from the west. This should result in generally decreasing rain chances through the end of the week, though a weak mid-level trough along the Mexican coast could move enough to the north to bring some showers or thunderstorms later today.
This morning, high pressure is ridging west into the Gulf of Mexico from the Atlantic while a weak trough is moving west across the southwestern Gulf of Mexico. To the north and extended frontal boundary and cold front stretches all the way from Montana to Missouri and the Ohio Valley with a low located over eastern Canada. A warm front extends east from the low across southern New England to the adjacent Atlantic. In the west, high pressure is over Nevada with scattered lows along the West Coast.
At the upper-levels, we still see a slightly less amplified flow. The low pressure trough to our east has shifted further east to the eastern third of the country. To the west, the large high pressure centered over the Great Basin area has expanded east into the western Plains and West Texas.
A chance of showers and thunderstorms will persist today as moisture from a disturbance over northeast Mexico works its way north. Meanwhile, the upper-level high is building to the east, bringing slightly drier, more stable air to our area. This will result in rain chances decreasing on Thursday and Friday. A slight chance of rain will reappear on July 4 as the high weakens and shifts back west some, allowing more Gulf moisture to flow into Southeast Texas. Still, we can look for fairly typical July 4th Weekend weather with only a slight chance of isolated thundershowers.
The Tropical Atlantic Basin remains quiet overall and storm development is not expected at this time.
