Area Forecast Discussion National Weather Service Tucson AZ 148 PM MST Sun Apr 5 2020

SYNOPSIS. Dry conditions and warm daytime temperatures through Tuesday. A weather system will bring a few showers, cooler temperatures and windy conditions Wednesday through early Thursday. A slight chance of showers will prevail late in the week.

DISCUSSION. Still watching a storm system off the northern California coast this afternoon that was forecast to drop slowly south along the California coast through Tuesday. Thereafter, models showed this system moving inland Tuesday night/early Wednesday morning with showers spreading from west to east across Arizona. Strong and gusty winds along with cooler temperatures will accompany this system, with the strongest winds on Wednesday afternoon and evening. Coldest readings can be anticipated Thursday before temperatures gradually rebound Friday into the weekend as the system exits the region. Still not expecting too much rain or mountain snow across southeast Arizona, with the best chances of measurable precipitation occurring Wednesday afternoon and evening. Can't rule out a thunderstorm or two Wednesday afternoon and early evening.

AVIATION. Valid through 07/00Z. FEW-SCT clouds AOA 20k ft AGL, with some mid level cloud decks of SCT-BKN AOA 15k ft AGL expected later this evening through Monday morning. Back to SKC Monday mid morning into the afternoon as cloud decks shift south into Mexico. Afternoon SWLY surface winds will reach 12-18 kts with gusts around 20-25 kts again on Monday, decreasing during the evening. Aviation discussion not updated for TAF amendments.

FIRE WEATHER. Dry conditions prevail through Tuesday as minimum RH values remain generally in the 10-15 percent range. A pattern shift then allows for increasing shower chances on Wednesday/Thursday, with a slight chance of thunder during the afternoon/evening. Possible showers linger northeast of Tucson on Friday, drying by Saturday. Gusty afternoon 20-foot winds remain through much of the period from a southwesterly to westerly direction. The strongest winds are expected on Wednesday with speeds sustained 15-22 mph, with gusts around 30 mph.

TWC WATCHES/WARNINGS/ADVISORIES. None.

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.

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 numerous 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.
