SPC Day 1 Fire Weather Outlook Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0944 AM CST Wed Jan 17 2024 Valid 171700Z - 181200Z ...NO CRITICAL AREAS... The previous forecast (see below) remains on track, with no changes or additions made. ..Squitieri.. 01/17/2024 .PREV DISCUSSION... /ISSUED 1149 PM CST Tue Jan 16 2024/ ...Synopsis... A midlevel shortwave trough accompanied by strong westerly flow aloft will impinge on the central Rockies during the day, promoting a deepening lee cyclone over the central High Plains. Along and south of this feature, 15-25 mph sustained west-southwesterly surface winds (with higher gusts) will develop across much of the southern High Plains during the afternoon. Here, strengthening downslope flow will contribute to 15-25 percent minimum RH, though RH reductions should be marginal where the strongest surface winds are expected (i.e., east-central NM into the western TX Panhandle and in the immediate lee of the high terrain in eastern NM). While locally elevated fire-weather conditions are possible across the region, the limited wind/RH overlap and marginal fuels preclude Elevated highlights. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1300Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0639 AM CST Wed Jan 17 2024 Valid 171300Z - 181200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected in the conterminous U.S. through tonight. ...Synopsis/Discussion... In mid/upper levels, broadly cyclonic mean flow will be maintained over most of the CONUS, downstream from a synoptic ridge that will move over the Pacific Coast around the end of the period. A cyclone that moved ashore during the prior overnight period has devolved to an open shortwave trough over OR. This feature should deamplify gradually as it rapidly crosses the northern Great Basin to central Rockies today, reaching MO and OK by 12Z tomorrow. Though a flash or two cannot be ruled out as the associated midlevel cooling/ moisture cross the Intermountain West today, lightning potential appears too isolated, brief and unfocused to warrant an outlook area. Otherwise, troughing over the East will deamplify somewhat today as a strong shortwave exits the East Coast. A related/preceding surface cold front -- initially analyzed from the northern Bahamas across the eastern/southern Straits of FL -- will decelerate, weaken, and remain south of FL through the period. Lightning potential over land appears minimal at best, and too low for a 10% areal outline. Elsewhere, the air mass will be too dry and/or stable for thunder over the CONUS. ..Edwards/Dean.. 01/17/2024 Read more View the full article
