686 FXUS63 KSGF 052314 AFDSGF Area Forecast Discussion National Weather Service Springfield MO 614 PM CDT Sat Oct 5 2024 .KEY MESSAGES... - Highs in the 80s to low 90s through the weekend. Record warmth possible. - No measurable rain chances in the forecast through next week. Minimal chances for rainfall through mid-October. - Fire Weather conditions will be monitored as very dry air and no significant rain is expected through mid-October which will continue to dry fuels. && .SHORT TERM /THROUGH SUNDAY NIGHT/... Issued at 131 PM CDT Sat Oct 5 2024 The primary hazard expected over the next couple weeks will focus on fire weather concerns. Please see the fire weather section below for more details. As of 130 PM, visible satellite imagery showed clear skies across the Missouri Ozarks as surface high pressure continues over the region. Observations showed temperatures in the low 80s over portions of the eastern Ozarks, and the mid to upper 80s elsewhere. Highs are expected to climb a few degrees higher over the next few hours, topping out in the mid to upper 80s east of Hwy 65, and into the low 90s west of Hwy 65. This is 10-15 degrees above average, and could bring record to near record afternoon highs for our climate sites (see Climate section below). For tonight, overnight lows will remain in the low 60s across the entire forecast area. A cold front is progged to push through the region on Sunday, bringing slightly cooler temperatures behind the front. Afternoon highs however will still top off in the upper 70s to mid 80s, with the higher end of that range along the MO/AR border. Despite the "cooler" temperatures, highs will still be 10-15 degrees above the climatological normal for this time of year. With the passage of the cold front, a much drier airmass will push over the area, with RH values dropping into the 20-30% range. && .LONG TERM /MONDAY THROUGH SATURDAY/... Issued at 131 PM CDT Sat Oct 5 2024 No significant changes were made to the forecast in the long term, with dry conditions continuing over the region. A warming trend is expected to occur throughout the week, with highs ranging in the 70s and into the low 80s Monday and Tuesday warming up to the upper 70s to mid 80s by Friday. Looking ahead towards the middle of October, the Climate Prediction Center is highlighting the entire area in a 80-90% chance of below normal precipitation and a 50-70% chance of above normal temperatures (8-14 Day Outlook through October 18). With both CPC and ensembles pointing to drier than normal conditions and minimal rain chances, drought conditions are expected to either persist or worsen, so will need to continue monitoring. Towards the end of the month and into November, CPC drops the chances of below normal precipitation to about 50-55%. && .AVIATION /00Z TAFS THROUGH 00Z SUNDAY/... Issued at 611 PM CDT Sat Oct 5 2024 For the 00z TAFS, a cold front will push through late tonight into Sunday morning. With a dry air mass in place however, VFR conditions will persist through the period. Wind will become light and variable as the front moves into the area and then becomes northerly around 10 kts behind the front. && .FIRE WEATHER... Issued at 134 PM CDT Sat Oct 5 2024 Looking at the joint probability of wind gusts >20 mph and Relative Humidity <30%, models continue to show less than 5% chance through at least the middle of October. This would keep any critical fire weather and red flag risk low at this time, however elevated fire weather potential continues to exist. With the current dry fuels and additional drying fuels, we`ll continue to assess any red flag potential closely. Through this weekend: Dry and abnormally hot conditions will continue, with record to near highs possible each day. Rest of today...In addition to the abnormally warm temperatures so far today, relative humidity values have continued to drop throughout the early afternoon, with observations at 130 PM showing RHs in the 30-40% range over a majority of the area (with the exception of the eastern Ozarks currently in the 50% range). This, coupled with breezy conditions of 7-14 mph sustained winds gusting up to 15-20 mph has led to elevated fire weather conditions continuing through the remainder of the afternoon and evening hours, primarily west of Hwy 65. Sunday...Elevated fire weather is expected to expand across much of the area, with north-northwest sustained winds of 10-15 mph gusting to 15-20 mph. Minimum RH will dip to 20-30% across much of the area and 25-35% across south- central Missouri. Monday through Saturday (October 7-12): No rain is expected during this period. Temperatures will be slightly cooler but still above normal with highs in the 70s to mid 80s. Daily dry minimum RH values will range between 20-35%, with a 10% chance of winds >20 mph west of Interstate 49 on Saturday (Oct 12), but no other notable wind concerns. 1-2 weeks (October 13-19): Confidence in specifics decreases with time, but a majority of model data shows little to no rain through this time period. RH values are more difficult to assess this far out, but a majority of ensemble members show a dry airmass remaining in place and >50% probabilities for daily RH values dropping below 30%. Hard to give many details related to winds, but right now fewer than 10% of ensemble model members show winds >=25 mph any of the days in this period. Still, we will be watching closely given continued drying of fuels. We`re starting to see leaf fall begin in some areas which will begin to add to fuel load. Additionally, first fall frost and freezes occur in October with middle to late month the average time of occurrence across the Ozarks. && .CLIMATE...
