This bulk download tool provides the NWS text
in a raw form, hopefully directly usable by your processing system.
You can either provide a complete 6-character PIL/AFOS ID or provide
the 3-character base ID (e.g., AFD). The start and end
dates represent 00 UTC for those dates. The Zip format is useful as
the filenames will have the product timestamp, which is useful for
when the product format has ambiguous timestamps.
675 FXUS65 KSLC 191613 AFDSLC Area Forecast Discussion National Weather Service Salt Lake City UT 1013 AM MDT Fri May 19 2017 .SYNOPSIS...High pressure will temporarily build into the area later today into tomorrow, before another, weaker trough clips northern Utah on Sunday. && .DISCUSSION...The combination of the right entrance region to a jetlet over central Utah and weak 700mb directional convergence across the Great Salt Lake and west desert region is producing light precipitation over the Oquirrh Mtns and Stansbury Range and across higher elevations farther south in Tooele, Utah, and Juab Counties this morning. Updated the forecast to include isolated showers for this morning in these locations. Although stratus clouds stretch farther south all the way to Cedar City, any precipitation which falls from this deck will be spotty and not expected to be measurable as the 700mb flow becomes more divergent. The only other update this morning was to improve the sky cover over Kane County as the northerly flow is down sloping and clouds have been dissipating, so have gone with mostly sunny skies there. For this afternoon, several models are pointing at convection developing over the northwest and northern portions of the CWA, but inspecting recent forecast soundings from several models this looks overdone as the positive area is very minimal so have backed off from chance to slight chance and this may be overdone as far as thunderstorms are concerned. Rest of package in good shape. && .AVIATION...Some lake-enhanced showers are currently passing in the vicinity KSLC, the only impacts from these will be brief periods of cigs at or just below 7k ft. These showers should move away/dissipate in the next couple of hours and ceilings should remain above 7k ft for remainder of the day. Northwest winds will prevail until the normal diurnal southerly wind shift around 03-04Z. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...None.
