AVIATION. LIFR and IFR ceilings hung around longer than initially anticipated due to high clouds streaming in from the west. This prolonged the time it took for the dense fog to burn off. Starting to see ceilings lift now and visibilities increasing but have kept IFR ceilings in and 4 SM visibility for I-35 sites over the next hour. All sites will see VFR conditions this afternoon with southerly winds. MOS guidance suggested lowering visibilities late tonight ahead of the front, put this in for the I-35 sites but may need to be amended later. A dry frontal boundary will move over the region late tonight and shift winds to a northerly direction, wind speeds may reach 12 to 15 knots in some places by tomorrow afternoon.
PREV DISCUSSION . /ISSUED 347 AM CST Thu Dec 5 2019/
SHORT TERM (Today through Friday Night) . Current weather pattern across Texas is characterized by zonal west to east flow aloft as a short wave trough located over western Arizona/southeastern California continues its eastward progress. At the surface generally high pressure remains in place although the center of the high has continued to drift eastward into the southeastern US.
Quite a bit of variance exists between our western/Hill Country areas and the Coastal Plains this morning. Kerrville is our coldest location as of 3 AM, with a temperature of 44 degrees with a 38 degree dewpoint under clear skies and calm winds. Kenedy is currently 57 degrees with a dewpoint of 56 with calm winds, which has yielded dense fog. Both Kenedy and Gonzales currently sit at quarter mile visibilities. Fog is expected to continue to spread north and west this morning toward the I-35 corridor before mixing out by mid to late morning. As such, a dense fog advisory has been issued through 9 AM for the I-35/37 corridor from Pleasanton to Austin and points east.
Temperatures this afternoon are expected to warm into the mid 70s for most locations, which is about 10 degrees warmer than seasonal normals. Surface moisture will increase throughout the day, especially for the Coastal Plains, in response to the approaching system from the west. This will give us some decent cloud cover today after several days of cloud free skies.
The Pacific cold front is expected to move through the region overnight tonight into early Friday morning, and is still expected to be dry. Winds will shift to northerly behind the front on Friday, and will be a bit breezy. Skies are expected to quickly clear behind the front, and Friday should be a pleasant day with afternoon highs ranging from the mid 60s to the mid 70s under clear skies. Friday night will be chilly, with lows ranging from the mid 30s across the Hill Country to the low to mid 40s elsewhere under mostly clear skies.
LONG TERM (Saturday through Wednesday) . Saturday will be another great day for putting up holiday lights or any other type of outdoor activity, with highs in the mid to upper 60s under mostly sunny skies. A warming trend begins on Sunday as winds shift back to southerly. Highs on Sunday will be in the mid 70s with upper 70s by Monday with moisture and cloud cover on the increase out ahead of the next cold front that is expected to move through on Monday afternoon/evening. This cold front may bring some rain, both along/ahead of the front and perhaps also post frontal with some overrunning potentially setting up. However, for now only show 20 to 30 percent chances of rain for Monday evening through Tuesday, and QPF should be fairly marginal. This cold front will also bring much cooler temperatures. Highs on Tuesday and Wednesday are expected to be in the mid to upper 50s with lows on Wednesday morning in the 30s with northeasterly winds.

Ad by Google
I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.
The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
