Warm and dry conditions will occur for most areas today, although a few afternoon thunderstorms are expected over the southern and central mountains. Changes begin on Saturday with showers and thunderstorms increasing throughout the day, becoming fairly widespread on Saturday night into Sunday. Locally heavy rain will be possible for a few locations with a good soaking rain for mainly areas. Unsettled conditions will continue on Monday. High temperatures today will range from 5-10 degrees above normal, then decrease to below seasonal levels by Sunday afternoon. (Please visit http://weather.gov/gjt for more information.)

High pressure remains overhead today with plenty of sun and warm temperatures expected. Some isolated showers and storms are possible over the San Juans and may reach as far north as the central mountains. Expect similar conditions tomorrow. An approaching cold front will bring an increased chance for widespread precipitation through the weekend. This front will also cause some gusty winds for eastern Utah and far western Colorado. (Please visit http://weather.gov/gjt for more information.)

Strong high pressure over the western United States will dominate the weather today through Thursday. High temperatures will warm back to above normal with only a slight chance of late afternoon rain showers over the San Juan mountains Thursday afternoon. Friday through the weekend, a strong Pacific storm will approach then move through the area. It will bring increasing clouds and wind, with the potential for widespread rain. Areas of heavy rain will be possible as well. (Please visit http://weather.gov/gjt for more information.)

A bank of low clouds will slowly dissipate and move east over northwest Colorado and northeast Utah this morning, with patchy valley fog elsewhere. High pressure will bring warmer and drier conditions through Thursday, then another strong Pacific storm will bring the potential for widespread rain again Thursday night through Monday morning. (Please visit http://weather.gov/gjt for more information.)

The upper level Low Pressure system is dropping onto the northern plains this evening with a drier and less unstable air mass working in from the west. A few storms may persist from Vail Pass northwards tonight. Otherwise clear skies may allow some fog to form mainly in western Colorado. The high pressure builds in from the west for a strong warming trend through Friday. The next Pacific trough works inland late this week for a chance of showers next weekend. Timing of the showers is still somewhat uncertain. (Please visit http://weather.gov/gjt for more information.)

Showers and thunderstorms will continue through this morning and into the afternoon as a strong low pressure system moves through the northern Rockies. Storms will continue into the evening before drier air moves in tonight. Expect moderate to heavy rain and gusty winds with storms. Localized flooding is possible especially where significant rain occurred yesterday. Skies will clear out from the west through the evening with storms coming to an end tonight. High pressure will build over the area Tuesday through Friday with a dry and warming trend. Moisture and unsettled weather look to return by the end of the week into the weekend as another low pressure system moves into the Great Basin. (Please visit http://weather.gov/gjt for more information.)

Breaks in the clouds may allow some rainshowers and thunderstorms to form this afternoon over eastern Utah and southern Colorado. However, a bigger push of moisture is expected overnight for southern portions of the forecast area and with already saturated ground in place, the chance for Flash Flooding is that much greater. For that reason, a Flash Flood Watch has been issued for areas south. Drying conditions expected Monday afternoon onwards. (Please visit http://weather.gov/gjt for more information.)

Showers and thunderstorms...some with moderate to heavy rainfall will impact the Flash Flood Watch area over the southern San Juan mountains and adjacent valleys over the next 1 to 2 hours. Rainfall rates may approach an inch per hour and even though storms are moving...training storms...will be a threat for runoff in areas that received heavy rainfall last night. Wind gusts to 45 mph will also be threats from these storms. (Please visit http://weather.gov/gjt for more information.)

The left image shows an area of showers and storms that is moving to the northeast this morning. Behind this area, expect clearing with another chance for precipitation to refire this afternoon and evening. The right image shows storm total precipitation amounts according to our radar. Members of the public have also called and reported the following rainfall amounts to include: Silverton 1.12 inches, Durango 1.41 inches, and Trimble 1.73 inches. (Please visit http://weather.gov/gjt for more information.)

Plenty of moisture surging northward this morning will continue to move northward across the area leading to widespread showers and thunderstorms as a strong low pressure system tracks through the region. Expect heavy rain, strong gusty winds and some small hail with storms that form. Some localized flooding with mud and debris flows is also possible due to heavy rainfall rates. Unsettled weather will continue through the overnight hours into the day on Monday, with drier air slowly filtering in from the southwest through Monday evening. Drier and warmer weather is expected Tuesday through Thursday until the next storm system impacts the area Friday into the upcoming weekend. (Please visit http://weather.gov/gjt for more information.)

Radar update at 5:40 am: Moderate to heavy rain is currently moving through southwest Colorado into central Colorado. Flooding has already been reported in the Durango area where as much as 1.5 to 2 inches of rain has fallen based on observations. More thunderstorm development is expected this afternoon into the overnight hours with heavy rainfall as a strong low pressure system tracks through the region. If you have any rainfall reports or flooding reports, please let us know! Thanks! (Please visit http://weather.gov/gjt for more information.)

Mostly sunny skies and warm, above normal temperatures will prevail today as high pressure rebuilds over the region ahead of the next storm system to impact the area Sunday and Monday. Enough moisture will remain for isolated afternoon storms over the higher terrain. Monsoonal moisture will increase on Sunday ahead of a low pressure system set to move through the area into Monday. This will bring widespread showers and thunderstorms Sunday into Monday with some strong storms possible. Expect heavy rain, strong winds and hail possible with storms that form. Drier air will move in behind the departing low on Tuesday with the next chance of precipitation coming towards the end of the week. (Please visit http://weather.gov/gjt for more information.)

Expect partly cloudy skies today with warm, above normal temperatures. Scattered storms will occur this afternoon mainly over the higher terrain as a disturbance brushes the north with a slight increase in moisture. Saturday will be mostly dry with a few storms over the higher terrain. Significant monsoonal moisture returns on Sunday into Monday as a low pressure system moves through the area, leading to an increase in shower and storm activity with locally heavy rain possible. Some storms may be strong with the possibility of strong outflow winds and large hail. Temperatures will cool to more seasonal levels by Sunday.

A slight increase in thunderstorm coverage is expected Friday into Saturday as moisture moves up from the south with isolated thunderstorms for the valleys and scattered storms in the mountains. Significant monsoonal moisture returns Sunday into Monday leading to a fairly widespread rainfall event with locally heavy rain possible in a few locations. Temperatures will cool to more seasonal levels beginning on Friday. (Please visit http://weather.gov/gjt for more information.)

Warm temperatures will continue the next few days with most thunderstorm activity limited to the southern mountains and valleys.
