Denver's Tuesday Discussion

A tranquil day for the front range as an upper level ridge moves across area and high pressure in control at the surface. Temperatures at 700mb are shown to rise 10C between 00Z Tuesday and 00z Wednesday by the 12z run of the GFS. As the ridge axis moves across the area by 18z Tuesday a southwest flow will result bringing warm dry air from the southwest. Our low temperature Tuesday morning could be effect by moisture and cloud cover shown on both the GFS and NAM. Light winds will begin to pick up at the end of the period as the ridge pushes off to the east and a large trough bears down on the west.

KAMA Friday Forecast

As upper-level system and sfc cold front moves on, expect conditions to dry out and cool off.
High temps should be in the mid to upper 60's with the low in the mid 40's. Winds will be high in the upper 20's. Precip will mostly be during the early hours, then drying out as the day progresses.

KAMA Wednesday 21 Forecast

Stormy and cool conditions continue as the the weak low persists, but drier conditions will return later in the week. Highs tomorrow will be in the mid to low 70's and the low will be around 50. Scattered showers and thunderstorms could produce locally heavy rain and windy conditions. A better chance of thunderstorms will be on Thursday as a strong system moves into the area with the possibility of severe thunderstorms.

Tuesday's Discussion For KAMA

The period starts with the western US under a 500mb ridge and a deep trough just moving onshore. The 0z GFS shows a short wave ejecting out of the trough with surface low pressure, and precipitation forming by the end of the period. The NAM does not show this and is thus much drier. There is enough moisture and instability that afternoon storms are quite possible even without upper level support. Temperatures rise a few degrees from Monday with a little increase in thickness and heights.

Forcast for Saturday 17 April 2010

Rain Rain go away! The cold front has passed through the region this morning bringing cooler temps, but a low pressure is set up south of Amarillo and is bringing rain to the area. This low is drawing moisture up from the gulf which is converging with the cold front. The low seems to be a slow moving system and both GFS and Eta show more rain in the forecast for Saturday. Rain totals could reach 1/4 of an inch. Highs should reach the mid 50's with lows around 40 for Saturday morning. Winds should be around 10 - 20 mph with gusts near stronger storms.

KAMA Forecat for Friday

The area seems to be a focal point, with strong moisture transport from gulf associated with SE high in thegulf area, aswell as a low to the east. A cold front ahead of high pressure building in the centre of the country will help to focus the precip. Expect high to be in low 60's with the low temp in near 50. Will be overcast throughout the day, with precip mostly showers. Wind in the teens, but my gust into 20's due to a local thunderstorm activity.

KAMA Wednesday April 14

Stormy weather continues even as the cold front passes. Temperatures will be lower behind the cold front with the high only in the mid 60's. The low will drop down to the mid 50's with continued windy conditions. With good low level moisture values and marginal daytime heating the chance for afternoon and evening thunderstorms remains high but any precipitation will be localized.
