Where We Stand
Through May 4, the valley has accumulated 241 GDD (base 50°F), with 63 of those coming in just the past seven days. That single-week figure reflects what the thermometer confirmed: a high of 86°F paired with a low of 39°F — a 47-degree swing that compressed a lot of thermal work into a short window while keeping nights cold enough to slow vegetative momentum. Precipitation for the week was essentially nothing, 0.02 inches. Bud break was recorded April 4, putting us at day 34 of the active season, and the vines are currently in pre-bloom.
The Week Ahead
Models show a descending temperature profile over the next seven days: highs of 72°F, 76°F, 72°F, 68°F, 57°F, 67°F, and 75°F. Precipitation is forecast at trace levels — 0.01 inches on day five, nothing on the remaining six days. The mid-week dip to 57°F is meaningful in the context of where the vines are. Pre-bloom fruit development responds to accumulated warmth, and a single cooler day mid-sequence won't erase the week's gains, but the overall trajectory is a moderation from the 86°F spike rather than a continuation of it. The dry conditions hold throughout.
Season Context
241 GDD at day 34 reflects a season that has moved with purpose. The April 4 bud break date and the current pre-bloom status are consistent with that pace. The 86°F high this past week is the kind of reading that pulls the season forward in a concentrated burst — the question the coming weeks will answer is whether that acceleration holds or whether cooler temperatures moderate the path to bloom. The forecast pattern indicates a pause rather than a reversal. Bloom timing and the thermal conditions surrounding it are what the season now hinges on.
