NWS Grand Junction, CO wrote its last area forecast discussion before the first event at Mar 24, 3:55 PM MST, 25 minutes earlier.
Area Forecast Discussion National Weather Service Grand Junction CO 455 PM MDT Sun Mar 24 2019 .SHORT TERM...(Tonight through Monday night) Issued at 210 PM MDT Sun Mar 24 2019 In true spring-like fashion, we have scattered showers and isolated thunderstorms dancing ENE across the forecast area this afternoon in a moderately unstable atmosphere. This activity will be diminishing this evening and coming to a complete end around midnight. No significant precipitation is expected, although some graupel or small hail and cloud-to-ground lightning strikes may occur through 7 pm. Once this round of showers shuts down, we are looking at a significant drying and warming trend setting up for the first part of the week as high pressure builds overhead. Expect a lot more sun on Monday with clear and cool conditions Monday night. Temps will rebound to near normal by Monday afternoon. .LONG TERM...(Tuesday through Sunday) Issued at 210 PM MDT Sun Mar 24 2019 High pressure shifts east with dry and warm southwest flow settling in through midweek. Temperatures will jump a good 5 to 10 degrees Tuesday and will top out on Wednesday with readings reaching the upper 60s to lower 70s in the lower valleys with 60s arriving over the high valleys and some mountain locales. With the warmer temperatures will come deeper mixing, resulting in an increase in surface winds as gradients tighten up. So expect breezy weather Tuesday afternoon and for much of the day on Wednesday, possibly pushing into Thursday as we await the arrival of a strong cold front. This front will sweep cooler conditions in sometime Thursday with the cooler weather sticking around through the weekend. Driving that front is a series of Pacific waves waves that will bring another round of unsettled weather. Models are not in prime agreement with the track or timing of individual features, which shutters confidence a bit. But trend is locked in with cooler and wetter pattern to close out the week. Just how cool and wet remains somewhat in question. The warmer weather early in the week will have some impact on our smaller waterways and is discussed in more detail below. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Issued at 448 PM MDT Sun Mar 24 2019 Scattered showers and thunderstorms will continue developing over northwest and central Colorado as an upper trough moves overhead. Expect widespread ILS CIGS at airports from I-70 north plus KASE with periods of MVFR and IFR conditions under stronger showers until about 04Z then VFR conditions should prevail. Fog will be a possibility overnight along the CO river due to rapid cooling after today's rain and snow. && .HYDROLOGY... Issued at 210 PM MDT Sun Mar 24 2019 Temperatures are expected to climb above seasonal normals Tuesday and Wednesday. The warmer weather will help to compact the snowpack and increase melting, especially along south facing slopes. This in turn may lead to an increase in water flows on area creeks, streams and smaller rivers. The mainstem rivers will be slower to react, but an uptick in volume should be expected over the next few days. Temperatures are expected to cool back down by the end of the week with snowmelt slowing. && .GJT WATCHES/WARNINGS/ADVISORIES... CO...None.
